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)
reverse?
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)
preset banks
bit crushing
other:
effects - scrub, reverse, glitch, delay, pitch bend(speed)
ultimately if this goes well I would like to design it as a product
Details
Things I might need:
not sure if I would want to have some SRAM on here for more ease of messing with the data
I need to build the mic input circuit and possibly something for the output
the main problem with my project is going to be the coding, I know very little code and would appreciate any help.. I might make a post detailing how I want it to work
there are some tutorials i will link to on how to get a WAV file playing on your propeller via SD card
