[sdiy] Fast lcd display like digitakt

[Benjamin Tremblay]

I’ve been working on some virtual synth code, and also learning how to send nrpn midi messages. It’s all going well but for midi controller and synth projects I envision a paged Oled display with virtual knob animation and maybe a touchscreen. 
What kind of hardware do I need for this? I purchased 2” and 3” displays from Amazon and tried out sample code on an arduino mega and then ran it on a Teensy LC.  I have a teensy 4 and a pico and some Stm32F401 boards. 
I am using the Adafruit gfx library and so far using an offscreen canvas is too slow.
Should I use a 1-bit display? Repainting the screens is sluggish; maybe 2fps max. Should I use a faster SPI implementation? I know teensy LC is slow. Should I use another graphics library? 
I’m going to assume displays are nice for things like waveform editing and such. I have seen some fast oscilloscope demos on Oled displays. 
Hm.
