  1. Upcoming MBHP_MF_NG module

    Well, there are a few reasons. It's a 7 potentiometer pedal with a switch I want to control with a relay. I have a midi processor that sends batch CCs to pedals. The midi processor has presets that are called up from a PM sent from my foot controller. This enables me to automate almost everything in my rig. I use it for my Moog Moogerfooger pedals which don't have a built in preset system. Also, I want the pedal to work regardless of the digital control. I am concerned that adding more function to a pedal simply adds more things that can go wrong on the road. I want to be able to manually adjust the pedal even if the control circuit is not working. There will also be times when I'll need to start from a certain setting and adjust the knobs manually. I don't want it to jump from the digital setting to wherever the knob happens to be. Hopefully this makes more sense now. I didn't state my full intentions in my previous posts.
  2. Upcoming MBHP_MF_NG module

    Thanks for taking the time to send a response. In my situation, I'm not editing audio real time. I'll simply be quickly moving them to a position and they'll be staying there. Are you having EMI problems even when the fader is stationary? Or does it occur with the motor is moving?   I think the fuzz factory may take the motor brush noise while moving quite well as an addition to the effect :thumbsup:
  3. Upcoming MBHP_MF_NG module

    I'm interested in using the MF_NG module to control a small fuzz effects pedal's pots. I was wondering if this would work find for motorized rotary poteniometers instead of high quality faders. I love to DIY, but after around 50 hours of day job and 30 hours running a studio, I don't have too much time to learn programming in depth. Could this provide a simple platform for me to send Midi CC's to individual motorized potentiometers to control them? I would be manipulating the pots real time with a controller as well as sending batch CC #s from a Midi preset box. It looks like that's exactly what it does, but since this entire world of digital/midi is a bit new to me I wanted to doublecheck.   Also, I've read previous mention of noise making it's way into audio through using motorized pots. If I'm using this for a fuzz pedal, I'm assuming I should keep the power and ground from this circuit completely isolated from the fuzz pedal? Any other tips?   Thank you!
  4. I could go the motorized potentiometer route. Mouser has the Bourns motorized pots in stock, but they're 2" deep. If I build a custom enclosure, that wouldn't be too much of a problem.
  5. Hi, This is my first post here. I'm not new to building analog circuits, but have no experience with programming or working with digital. I'm hoping that this might be the right place to ask for advice on where to start. I don't know if any if the MIDIbox projects are remotely close to what I'd need for this. I'm looking for a way to save knob settings and bypass (relay) status from an effects pedal. basically, I would like to have a circuit that does exactly this: http://youtu.be/2XaV-XpgnEU The only difference would be to be able to implement them into a couple different pedals. Things that I do know: The pedal would have a midi in connector to receive midi PCs. The pcb would have to be small. Or I would have to be able to break it into different sections that could be connected externally. There would be a switch added to the pedal that would allow me to save the current knob settings and bypass status to be triggered using the last PC# that was sent to the pedal. I would take the potentiometers off of the original circuit and connect the pads to the midi controlled circuit. The midi controlled circuit would somehow replicate the resistance that would be set by the original potentiometers. The bypass would use a dpdt relay and an LED to show the bypass status. And this is about all I know so far! It's very difficult to find any info on this and I'm not sure if it's something that has been done in this way. If you can lead me in the right direction, I would really appreciate it. As of right now, I'm pretty overwhelmed by the sheer number of projects out there. Thank you!
