I programmed the fifth mode to talk to my drum sampler but had to restrict the instruments to the eight I programmed. Once I get this working, I should be able to place any number of sound effects on any number of SD cards, and the EWC_Box can play them.
Drum sampler played by EWC_Box
I repurposed a garage door opener remote to operate the PRandomize button at a distance. I had a big red button mounted in a decorative tin can, and I connected the transmitter, and the receiver went inside the enclosure so that I could trigger notes from the next room. I think this makes the project more approachable.
Wireless button controlling the PRandomize button
I produced a draft of mode5() which combined melody and percussion for the first time. I succeeded in rattling off a prandom set of notes while a drum loop cycled in the background, but I need to improve it.
I listened to mode5() for a long time and took notes on what I did not like. I had hung notes, empty melody channels, and too many simultaneous melodies playing. I fixed those first ones, then got distracted because I wanted to change modes quickly instead of mashing the Mode button five times after each restart. I added a feature to the serial communication that lets me switch by sending a single digit.
Changing modes and help menu
I finished mode5() by making the volume controls "live." I can generate any number of percussion and melody instruments, but now I can adjust the balance between them while playing to get the best sound, whether I want to accentuate a solid beat or focus on some delicate instruments.
I wanted a mode that automatically changes parameters to give the music a dynamic sound. I created mode6() with only percussion. Most of the functions came from other functions, but I had to implement a timer system that periodically changed the sound. The result was some background music that never got stale.
