I plan on using the parallax propeller to make a sampling keyboard. Hopefully the functionality will be based on the casio line of sample keyboards as well as the korg microsampler with the possibility of adding some of my own features.
For the project I just mainly want to get to the point of playing a sample when the key (touch pad) is pressed and having polyphony (limited polyphony is fine, maybe 3 or 4 voice but hopefully more). Everything beyond that is extra but I do have a lot in mind.
Casio sk-x functionality:
record sound, sound is stretched across keyboard at various speeds (one shot and loop)
Korg microsampler functionality:
same as sk-x
trigger loop per key
chop incoming sample to group of keys
key select per sample (multi-sample instrument or split keyboard/drums/clips)
effects - scrub, reverse, glitch, delay, pitch bend(speed)
ultimately if this goes well I would like to design it as a product
Things I might need:
not sure if I would want to have some SRAM on here for more ease of messing with the data
