s4ndp4pper Posted July 20, 2003 Report Share Posted July 20, 2003 Hi... I'm making a Mb64 and are planning for it to have a pair of 6.3mm (1/4") jacks, so i can connect control pedals like on a synth.Can i connect the jacks directly to the AIN module just like pots/sliders, or do i need extra resistors and stuff?I also plan to connect jacks to the DINX4 (for foot switches) and have the same dilemma about that.Another question btw:I thought about connecting the DINX4's expansion port (J2) to a 9pin D-SUB, so i can connect another DINX4 as a external device (are planning to making a simple keyboard, Kraftwerk style :-). Can i do this, or will i get random MIDI messsages whenever the port is not connected?/J Quote Link to comment Share on other sites More sharing options...
pilo Posted July 21, 2003 Report Share Posted July 21, 2003 if it's expression pedal (for volume for example) you can plug them with stereo jack on AIN modules, if it's just a switch pedal, connecet them on a DIN module ;)For the external DIN, I think it work if the cable is not too long... (don't exactly how long it can be) Quote Link to comment Share on other sites More sharing options...

pay_c Posted July 23, 2003 Report Share Posted July 23, 2003 That can be pretty long!! Its just an digital on or off. I would guess at least 5m or more (especially if u you use a shielded cable!).If you should encounter problems, or want to make it even longer, you can lower the R at the depending pin of the IC, which pulls the pin up to 5V (the original R is 10k I think, so you could go down to 4,7k or so). But I would rather first try it out with the original R, so the IC doesn´t get blown accidentially (although this shouldn´t happen as long as you keep the R above 1k).Just use a shielded cable and everything should be pretty fine up to 5m or more.
