hi guys,
i just got an arduino two days ago in hopes of making a midi -> din sync, cv/gate, and dcb converter. i have midi in to cv/gate and din sync working.
[..]
/* MIDI to CV/Gate converterError in HZ due to 256-bit resolution of PWM (f_desired - f_synthesized)
0 A0
0.0988 A#0
-0.2105 B0
-0.1113 C1
[...]
}
Hey, cool idea, doing it with PWM! But how audible is the Hz error in the upper octaves? Has anybody meassured the real errors using a 10bit DAC chip or high accuracy resistor ladder version?
I guess the errors would stay easily below 1% even on a 0-10V range... I'd like to emulate smooth glides/portamento with an analog feeling 
How good are commercial MIDI to CV converters?
Cheers, Oli, planing to build a MIDI/CV converter for his tenorion
