Using Android 6.0 midi?

Hi.

Just installed KatKiss-6.0_TF300T_015.zip on my TF300T yesterday evening since I wanted to try to get the "nmj - Network midi for Android" (www dot humatic dot de slash htools slash nmj (new user, can't post links...)) to work. If I try to run the nmjServiceSample app I get a null response when trying to get an instance of the midi service "m = (MidiManager)getSystemService(Context.MIDI_SERVICE);". If I run it in a virtual machine, then it works fine.

Are the midi services disabled in the kernel? Can I enable it somehow? Does it require a ROM update?
[Transformer TF300T Q&A, Help & Troubleshooting] timduru:
It now should be fixed in rom V016 :)

CONFIG_SND_RAWMIDI is currently enabled into the kernel.

there are two other settings related to MIDI it seems:

CONFIG_SND_RAWMIDI_SEQ

CONFIG_USB_MIDI_GADGET

also:

Virtual MIDI soundcard

MOTU MidiTimePiece AV multiport MIDI

UART16550 serial MIDI driver

Generic MPU-401 UART driver

that are not enabled currently

What are you trying to achieve ?

access an external usb midi controller connected to the tablet through that app ?

yes
[Transformer TF300T Q&A, Help & Troubleshooting] Lalulilelo:
It is fixed for me!

I had switched back to Lolipop because of that.

It's smooth and load fast on Youtube 720p50, Twitch, TV Orange.

It's now the best video experience I have had with my TF300T (can't talk about other aspects yet).

Many thanks!

What I'm trying to achieve is to connect a midi controller via the network using qmidinet from my Linux machine.

Or, eh, in reality I'm just trying to avoid buying a docking station with USB extensions... :o

Although it would be interesting to be able to connect a midi controller via wifi to the tablet.

Oh Great! i'll try out the new build, been the major problem i've had making the jump from 5.1.1 to 6.0

I'll let you know the results. Thank You.

Thanks, it seems to work and on waking the icon does show it's connected, however my new Messages only come through a few seconds after waking the device and often in the wrong order. Any idea why that is?

[Transformer TF300T Q&A, Help & Troubleshooting] timduru:
That sounds like doze mode, you basically need to exclude apps and system parts that you don't want to doze in the battery optimization settings.

The keep wifi on during sleep only acts at the wifi driver level.
[Transformer TF300T Q&A, Help & Troubleshooting] UndisputedGuy:
Thanks man, that did the trick. Any idea why my mp4/mkv thumbnails all show as corrupted? The videos themselves work fine and while I initially thought it was just my old video files getting corrupted, even new ones I download have a distorted thumbnail. There's lines of green and purple over them

We don't make mistakes, We just have happy accidents.
[Transformer TF300T Q&A, Help & Troubleshooting] timduru:
Yeah I noticed that too, most likely linked to the fact that it's using the hardware accelerated gpu codecs

while they now work fine to play video it seems that they have issues to grab a thumbnail from.

Not sure why yet, but for the moment I think it's more important to have hardware accelerated video again than thumb, so I'll keep like that .
[Transformer TF300T Q&A, Help & Troubleshooting] sergiolopezsan:
3 things to improve the rom, for timduru:

1) Could a long press onto the recent apps button work as a switch for the previous app rather than using a fourth extra button?

2) Could the power menu show an option to take a screenshot?

3) Is there any way to avoid installing some gapps and replace them with the official apps by Google? eg: Google Camera, the app for music, the email app, etc.

Thanks.
[Transformer TF300T Q&A, Help & Troubleshooting] timduru:
You can configure it like that if you want:

Settings => UI => NavBar buttons settings => set long press action on recents to "switch to previous app"

Settings => UI => uncheck "show switch to previous app Nabar button"

Overall I personally prefer a dedicated button, it's faster to switch than long pressing.

It'll make even more sense when katkiss multiwindow is back as it allows to switch quickly between MW apps.

Would be a bit of a waste,

as you already have a standard shortcut for that:

press power + volume down simultaneously

A "take screenshot" action is also available for long press or keyboard shortcut if you want too,

so you can set it to any key combination on the keyboard or long press on navbar buttons.

You could try the aroma version from the open gapps page, you can normally then select the apps you want

or just modify the package.

Just be carefull with the limited space on the partition and don't fill it up by adding too many things.

I tend to prefer to simply install the minimum through the recovery

then install everything that is available from the playstore from there.

That way it's not system apps can be easily backedup / restored through titanium.
[Transformer TF300T Q&A, Help & Troubleshooting] pdechad:
To me, Timduru, you've proven simpler is better. Thanks so much for all you do.
[Transformer TF300T Q&A, Help & Troubleshooting] UndisputedGuy:
Agreed. Thanks again, thought it might have been an issue on my end. Funnily enough I have one or two videos which are fine. Out of curiosity, what browser are you using on here? I'm using Stock but it seems to reload pages quite often when I switch back to it, despite me not really doing something that's using a lot of RAM or is intensive. Not a major issue though considering how fast the ROM is. Appreciate the work here

We don't make mistakes, We just have happy accidents.
[Transformer TF300T Q&A, Help & Troubleshooting] timduru:
Most likely depending on the codec used in the video.

I use stock too.

it doesn't reload here when I switch back to it though.

Hi all, recently loaded this on my TF300T using TWRP 3.0.0. I did a full data format (ext4fs?) before installing the ROM, Gapps, and SU.

I'm having wifi issues with this rom. Using wifi doctor I see that I'm only connected at 2mbps with a 80-90% signal strength. I have a robust ubiquiti router and AP and no issues with any other device (10+ on the network). Sometimes I get zero connection, sometimes I get full bars, but no actual connection.

Anything I can do to get the wifi back? Reboots and airplane mode tend to help, but the issue comes back quickly.

Also, how do you change the /data filesystem to F2FS?

Thanks!
[Transformer TF300T Q&A, Help & Troubleshooting] ebonit:
First of all you need "twrp_tf300t_kang_2.8.7.2" as advised by Timduro. You may find it for download in the forum. Please note, TWRP 3.0.0 either isn't able to format F2FS and unlikely for this Rom. So I would like to advise to exchange your recovery to TWRP 2.8.7.2 Kang.

After that start recovery and then go >-Wipe >-Advanced Wipe >-click on Data >-Repair or Change File System >-Change File System >-choose F2FS >-Reboot System. Click Data only no System or Cache!

After that follow the first post here: http://xdaforums.com/transformer-tf300t/development/rom-t3237867

That's it! WiFi will work then after a clean installation.
[Transformer TF300T Q&A, Help & Troubleshooting] Liamfm:
I've followed this to a T now:

Replaced Recovery with Kang

Format Data

Format /Data to F2FS

Install Rom

Install Super SU

Install Gapps Pico

Reboot

Install K.A.T App

Same problem - wifi is flakey - sometimes it connects, sometimes it doesn't. At one point last night it connected and held 65mb wifi signal and worked great. That lasted about 5 minutes and I was able to download a bunch of apps. Then it went to about 90% power at 1mbps and really won't do much. This is the case on different wifi channels (currently on 11, no others on that, but have tried 9 and 6), near or far to the wifi router, etc.

This problem didn't exist on the stock ROM. Is there some file (kernal?) I can take from stock and push to this?

Thanks!
[Transformer TF300T Q&A, Help & Troubleshooting] ebonit:
First of all, you did a good job! It seems like a clean installation and everything should be OK.

As far as I can remember such WiFi problems are in 98% of the cases caused by the router. Before you make any other efforts please reboot your router and check the settings.

If the problem still exists try an other free network. For instance at McDonnalds or somewhere else. If no positive result, please repeat the clean installation again without K.A.T App.

Good luck!
[Transformer TF300T Q&A, Help & Troubleshooting] Liamfm:
Okay, rebooted router - no change

Tried to connect to my mifi - no change - can connect, then within 30 seconds the speed had dropped to 2mbs and it acts as though it doesn't have internet (or is too slow to do anything). The original wifi network was wide open, the mifi has a password, so that doesn't effect it either.

I've tried the install without the KAT app and gotten the exact same results.

uggh - ROM seems so smooth, but all we use this thing for is streaming videos.

What else can I try? Can I flash a different radio via ADB or fastboot?
[Transformer TF300T Q&A, Help & Troubleshooting] ebonit:
Download the app WiFi Analyzer and check your network environment about strong close channels. Change your channel if needed.

Did you check your tablet within another free network away from yours?
[Transformer TF300T Q&A, Help & Troubleshooting] Liamfm:
Thanks,

I've checked it with my wifi off completely and just my mifi. No change.

My wifi AP is set to search for the best channel. I'm in a very rural area and the only other network is weak and on channel 1. I'm on 7 right now, but sometimes it will jump over to 11.

I forced it to 6 and 11 last night with no change

Just to add to this: We have 11 devices on the network at the moment, ranging from 2 laptops, 2 chromecasts, a fire stick, 2 thermostats, etc etc. This is the only one having issues, and only after upgrading from the stock ROM. On stock the OS was deathly slow, but the wifi was always stable. I'm thinking this is something in the OS, radio, etc and not a network issue.
[Transformer TF300T Q&A, Help & Troubleshooting] ebonit:
I'm sorry for that trouble you have. There are no similar experiences in the net.

The only one advise I could address to you is to try Cyanogen CM 12.1 "nightly" https://download.cyanogenmod.org/?device=tf300t. But it's based on Android 5.0. It's a widespread excellent rom. It's also fast and stable.

If you try it, please report the result regarding WiFi. Thanks!
[Transformer TF300T Q&A, Help & Troubleshooting] Liamfm:
Same general problem right from the beginning. It hangs at obtaining an IP. Then cycles through. After about 5 minutes it rebooted itself.

---------- Post added at 01:53 PM ---------- Previous post was at 01:48 PM ----------

After it rebooted I am up and running, but only 6mb.
[Transformer TF300T Q&A, Help & Troubleshooting] pastorbob62:
I understand that you have a high speed connection and are expecting more out of it, but 6 mbps is hardly slow. Where I live (rural central USA), that is the speed of our service and I watch streaming videos very often without any issues. I have even watched videos while updating apps without hiccups. But if you are used to much faster connection speeds, I guess it can seem snail paced.

That said, I have read in several threads about there being several versions of the TF300T, with a different radio on each one. It is possible you got one of the dogs, given that you mentioned having slow service even on stock. And that fact that it is your "Link Speed" between your router and tablet seems to indicate it as well. Have you tried it through another router to see if the problem is duplicated?
[Transformer TF300T Q&A, Help & Troubleshooting] Liamfm:
I don't have slow service on stock, and the 6mb is my connection to the router, not my overall speed. My ISP speed is 175mb if the device will connect that fast over the WiFi. For example, my link speed on my Android phone is 144mb. The WiFi on the tablet keeps dropping the speed to the router until it hits 1mbs. At that speed it basically hangs and won't do anything.
[Transformer TF300T Q&A, Help & Troubleshooting] pastorbob62:
Right, see my edited comment above. You replied before I could correct and clarify. Still not fully awake so my brain is a little foggy. ;)

Also, didn't you say in an earlier comment "On stock....deathly slow",?
[Transformer TF300T Q&A, Help & Troubleshooting] ebonit:
I'm sorry but now I give up!

I was following the last posts and I think your tablet including your installation of Timduro's rom is OK. It seems to be the problem only is your personal network with that very slow connection at the end. Where might be the bottle neck? Only you can find it.

Why did you never try another free network available at McDonalds or somewhere else as I recommended a few days ago? I suppose your tablet will work fine there.

Wish you good luck! :)

I have similar issues with wifi but I kinda write it off to having installed a used main board to bring my tf300t back to life after a hard brick. Would reinstalling firmware possibly help or is the firmware part of the Rom or is wifi in the Rock?

---------- Post added at 10:22 PM ---------- Previous post was at 09:58 PM ----------

Rom not rock :)
[Transformer TF300T Q&A, Help & Troubleshooting] Liamfm:
I have tried it on 2 other networks with the same results. My Mifi and my phone. Both drop the signal speed down to 1mps.

To clarify, when it was on stock, the responsiveness was very slow. The wifi worked flawlessly. It was more of a 'push a button, wait 20 seconds'. If you were ever downloading anything it was fast.

Is there a way to push a stock kernel onto the tablet? If so, directions would be great!

Thanks again all!
[Transformer TF300T Q&A, Help & Troubleshooting] ebonit:

Yes, it would! That's what I would finally like to recommend to you and to Liamfm too. I also exchanged my main board after a hard brick two years ago.

Clean up your tablet by a factory reset. Install the latest Asus firmware as advised by Asus. After that you need to flash TWRP 2.8.7.2@AEREA51 again. Then you may flash a custom rom your choice and your WiFi trouble will be repaired.

To do this, I've downloaded TF300T-US_epad-10_6_1_27_5-UpdateLauncher.zip, when I unzip it I get another zip file which quickly unzips and deletes itself (guessing this is a mac thing), and then a folder with a blob in it.

Which of these files do I want to push, and do I want to install via fastboot push system xxxxxx or via twrp?

battery drain tf300tg

Hi,

I've installed KatKiss 6.0 about month ago and everything works great except huge battery drain. After month of figuring out what is the cause of that battery drain I still don't have a clue. I installed #18,#22 and #23 of KK6.0, latest version of KK5.1 without any difference to battery drain. I tried few apps like Hibernation manager, Task killer, Greenify and none of them help. On attached history_battery picture between 10:30 to 16:00 my tf300tg is in sleep mode (closed) - wi-fi, gps and screen are off but there is is one thing which is almost all time actvie "Aktywne". I presume it must be some system process (I even tried how long battery last on clean install of KK6.0 - no other apps installed) but i don't know how to check which is it exactly. So i've made screenshots of two processes (kernel and system). If someone is able to figure out what is going on I would be gratefull. If I need to make any other logs, screenshots please reply here and I'll do it.

It has been the same to me for a couple of day, android system was killing my battery in few hour even if in standby (or, even worst, when switched off!).

The only thing I was able to discover is that a misteryous process called "various" was keeping alive system all the time preventing deep sleep.

After reinstalling greenify and enabling advanced feature, rebooting twice my tablet, this weird behaviour disappeared. Don't ask me why.......however is second time this happens.

Yesterday I upgraded my tf300 from crombi-kk 4.4. (some flaky behavior, plus I was tired of the 8 min boot times) to Katkiss Marshmallow, latest release. Wiped, reformatted to f2fs, and after a couple of hiccups flashed rom, gapps nano, and superSU. rebooted fine. then when trying to use titaniumbackup to restore settings I was told that tablet wasn't rooted. and superSU needed binaries. After several attempts to download binaries, and then reflash superSU, tablet eventually came up rooted. However there are a few issues:

1. ES file manager can't see the microsd card. It saw it in 4.4. TWRP 2.8 can see the microsd. What can I do make the microsd usable on the tablet?

2. I use the attached keyboard. pressing the lock key puts tablet to sleep, but no key on the tablet wakes the tablet. Have to use the tablet power button. pressing keyboard lock key in 4.4 woke the tablet. Is there a way to make it work again?

3. Are there some apps missing from gapps nano that might be causing the microsd and keyboard issues?

4. Titanium seems to be useless to get data and settings back. (eg browsers with bookmarks). I did a backup through TWRP before wiping. I am thinking of reinstalling the backup to get back to 4.4 and find another app to backup settings. do I have to wipe first and reformat? Is the danger of something going wrong make it not worth the effort? Better to recreate settings, etc.?

5. I notice that you have ver 7, nougatella. What do think of my wiping, formatting and flashing ver 7 to use rather than ver 6? Are there usability or stability issues still in ver 7?

thanks for any suggestions.
[Transformer TF300T Q&A, Help & Troubleshooting] ebonit:
First of all be sure that you have Kang TWRP 2.8.7.2@AREA. It's required in the first line of the install instruction in post #1. Then simply follow this install instruction

carefully

step by step.

You need to make a clean install. That means Format /Data through your TWRP. That's more than Wipe and takes about one hour plus. After that change /Data to F2FS. /Data only not /System or /Cache. Then flash the Rom of your choice, OpenGapps (pico, nano is too big) and SuperSU in one run ->Wipe Dalvik/Reboot. Missing Apps you may download later via Google Play. Good luck!
[Transformer TF300T Q&A, Help & Troubleshooting] apricoto:
Thanks for your help. I did flash the kang twrp, wiped, formattd data, set format to f2fs, installed 6.1, gapps pico, and supersu. so far all issues still exist. no microsd card in es file manager, (though twrp sees it), key board won't wake tablet. I found another user with the same missing microsd issue. I have also found that google, while restoring all the apps does not restore any data or settings. Is there a trick to making that happen? I haven't tried titanium bu to see if it works any better today than it did yesterday. not likely. keyboard integration and missing microsd card are the main issues at the moment.
[Transformer TF300T Q&A, Help & Troubleshooting] ebonit:
You are welcome! Using the thanks button will be greatly appreciated.

As far as you reported the Kang TWRP recognizes the SD card. That's fine. So it isn't no longer an issue. Please look for another File Manager in Google Play. I'm using "Cheetah Mobile" 4,4 * for many years. Missing data after format /data you may restore via Titanium backup. Go ahead!
[Transformer TF300T Q&A, Help & Troubleshooting] apricoto:
Um, no. I reported that the microsd card is still seen in Kang,while flashing; but Not seen in ES file explorer.. I have noticed that plugging in the microsd card into asus keyboard (using adapter) shows up in ES file explorer, but it won't show any of the files on the microsd card. I checked the microsd card in the windows laptop,, formatted to fat32, all files visible on laptop.

titanium backup can't see its restore file because it is on the microsd card. luckily I have a copy on usb, which I can plug into asus keyboard and try copying to 'device' folder on tablet. However, the tablet froze during copy, failed twice in rebooting. after 3rd reboot it now doesn't see files on the usb drive. It sees it the usb, but not any files . And no titanium folder seen in 'device'. (copy froze)

I have tried the cheetah file manager, it doesn't see any files on tablet, anywhere. does show a list of installed apps. that's all.

there seems to be something about 6, or a setting that I don't know about, that keeps it from seeing external drives.

also, any ideas re: the keyboard? No way to get the tablet to respond to keyboard when asleep, the way it did under 4.4.?

This has not been an inspiring upgrade.

do you think that things might work better if I install nougatella, 7.1? or likely be worse?. I see that it is still getting frequent updates.
[Transformer TF300T Q&A, Help & Troubleshooting] ebonit:
Independent whether you have done it or not, please use the recovery to format /data again. Then wipe cache and Dalvik. That will get you a

squeaky clean

system. Note that formatting data in TWRP takes an hour plus. Let it finish!

After that flash the ROM of your choice. With KatKiss - Nougatella #019 you will be up to date.
