Not dense. I was confused by the data sheet as well. Nothing jumps out at me on how to select between the effects. The smallbear video showed some breakout testing board that I haven't seen anywhere on the Accutronics website.
Their documentation is slightly off in terms of the pins for Out1 and Out2, but i think that part is negligible.
Still not sure how to switch effects; unless of course...no it can't be...they are all running at once?!?!!?
By the gods!!! A tap temp chorus's'ing plate-reverberber!!!
It is actually very simple to select programs. The selection is NOT done from binary like other DSP modules.
You simply use resistor dividers to very the voltage on GP101
Take a look at the second page here the first row of the table shows you the exact voltage you need to call the respective effect.
I would use a rotary switch and resistors to get better accuracy.
here are the voltage in respect to the effect
GP101 pin needs the following V to call each effect
Chorus = 0.0V to less than 1.0V (default effect)
Echo = At least 1.2V but no more than 2.1V
Plate Reverb At least 2.3V and no more than 3.3V
Hope this helps.
