Dear Marc,
Are suggestions still welcome at this point or is it better to wait until further notice ?
I vaguely remember a posting from you, that there might be another vintage character for the character section coming at one point, either based on another classic synth and/or with a few user-adjustable parameters. I like "vintage 1" a lot, it would be great if there was a parameter to adjust the balance between fundamental and harmonics. If you use eq instead, you would have to boost with a shelve filter (which would make it boomy).
Also fantastic for Analog Boost, if one could choose between a click and a prelapse of the waveform itself (same length as the click).
Lastly, a wavetable going from triangle to saw to square would allow a great blend of classic wave mixes, as would be one that goes from negative saw (ramp) to triangle to saw.
Happy new year to all at Access!
