Hey peeple,
I just wanted to put it out there that the patch base evolver editor (ios / mac) has a waveform editor where you can draw your own waves. I didn't realize that until I downloaded it and started using it. That means you don't have to fool around with other software to make and upload waveforms to the evolver's user slots, you can do it right in the editor and store as many as you want on the ipad. I really like the editor for setting up patches but I wouldn't say it is for live tweaking because the interface is a little on the crowded side and parameter changes are smoothed or buffered (i.e. getting snappy wah wah effects with the filter or quick chromatic tone changes with the oscillator frequency 'knobs' isn't really possible).
