Polyphonic D50 sampler synthesizer with ESP32 in YAMAHA DX21 Hardwer :)

Unfortunately, the motherboard of my dx21 synth is broken beyond repair. So she got new electronics. I have uploaded a code I wrote using Roland D50 sound samples.
So what everyone feared has come true. The Yamaha Roland DX-D50-21 :)

Abilities:

-4 d50samples
-TVA Envelope
- Course, Fine, Keyfollow
-The sampling frequency is 48000Hz.
- Signal on 16 bits or more
-The device is polyphonic up to 10 tones
- 2 LFO controlled 2 parametric EQ
-Upper Lower Choruse
-Reverb engine
-Roland D50sysex compatibility...
-hd44780 compatible LCD Display (Not implement more)
(If we are bored, we can listen to internet radio on it.)

Great! I didn't have the LCD on hand but uploaded it anyway. The default sound still played, sounding just like the video. I learned your song, it's perfect for the patch. Have you played with the code much since? I'm trying to figure out pitch bend. The "case" in the switch function is empty. Is it just too much for the esp to handle? Thank you for uploading this! Awaiting an LCD in the mail so I can dive deeper into the sounds.
