The popup menu lets you choose a different patch to edit. Click a button to edit the desired module. Most parameters are represented with sliders and numeric displays. Drag the sliders to change the parameter values. Note that the parameters are updated continuously, so that you can hear the effects of the changes as you make them.
Envelopes have graphic panes for editing.
To edit an envelope, click and drag on the black dots at the corners of the envelope's image. This is new, largely untested software. I highly recommend that you save all of the data in your MicroWave before you start using this editor. You may not charge the recipient in any way. You may not distribute the software by bundling it with other products.
