Digital Noise advice
2010-07-07 by eblake_smith
Hello everyone,
I recently completed my first few diy modules and have just started testing them. One of these is a CGS digital noise , and although its making a lot of interesting sounds, I'm not sure I've got all of the features working correctly. Opinions or advice would be appreciated. The digital noise I've built was the older version.
I'm getting good audio signals out of both the digital and filtered outputs. The digital outputs seem to effect the CV ins of other modules quite well also. Both LEDs are lit up when the unit is powered and they will flicker slightly in time with small changes in sound output. They are lit pretty close to solidly lit however, as the output pulses are always quite fast. The CV input appears to work fine, both my keyboard 1v/oct and ADSR change the sounds dramatically and the speed pot works when a cv signal is present, although not when there is nothing connected to the CV in jack (although I think thats how the circuit is supposed to work).
Where I'm having a problem is the clock in. If I plug something into the clock in jack the module goes silent, the LEDs go out and the module doesn't respond to the device plugged into it. I've tried both the ADSR and the 1v/oct signal from my keyboard and neither have an effect.
I'm wondering if this sounds like there is something wrong with the external clock input, or if I'm just not feeding it the right type of signal. I'm very new at this.
Thanks,
Blake.
