If this switch is ON, you will not be able to access different sounds on different MIDI channels. You are now ready to begin sequencing. There are eight parts available in the MC-505 that are assigned to MIDI channels as shown in figure 2. 3 Alternative Bank Select Messages Fig. The sounds in the MC-505 can be selected via MIDI by using bank select and program change messages.
Some computer based sequencers have patch lists or 'templates' available for various products.
These 'templates' allow you to select from a list of patch names, and will then send out the appropriate messages for you. You should check with the manufacturer of your particular sequencer to see if they have a MC-505 template available. If not, you must enter the proper bank select and program change messages manually to choose a sound. Controller 0 and 32 are used to select banks of sounds. Some sequencers combine these controllers into a single bank select number.
