Dear programmers and musicians, please pay attention to the Roland W30 sequencer. It has a "Record by key press" function that, when combined with real-time quantization, is rare. Considering its stability and lack of delays, I would like someone to port the Roland W30 operating system to a computer program on PC. This is possible because Roland uses an Intel 80196 processor.
Hier zijn de instructies te vinden: github.com/keirf/FlashFloppy/wiki/Host-Platforms#roland. Je moet in de IMG.CFG file wat veranderen, zie de voorbeelden op de site.
I changed them to get the contrast voltage in the range needed by the display. I needed it to be between approx. -10V and -5V, where the optimum for the display is around -7V +/-
Got it. I haven't changed them and now the optimal setting is when the pot is turned down all the way. Maybe it would be even better if I could turn it down even further. Not sure if this is worth disassembling the unit once again though. Anyway thank you very much!!
