I purchased the K4R module. How do you transfer the sounds to the module. Do you use Midi via or by means of cards ?
I purchased the K4 synth too, but do not shows info in the display, only shows one line of characters, the same, from left to right. Do you get any info about the electronics of this device, diagram of circuits or something like this ? I want to repair this keyboard. The only sounds are the amplificated noise. When I touch the taps of the volume potentiometer and using phones I can hear the noise of amplification. Do you know anyone who could help me about this ? Thanks for all
