Completely in suspense!!! :D

I have thought about doing the motorized turnpots, but I believe the cheaper ones have a really slow turn rate, which would make them unuseable for realtime. I have seen some fast ones, but I think they are almost twice as much as the motor faders.

I have had a couple weird problems with my midibox plus before, I think it might have been due to the 7805 overheating, but I am not shure as to what it is yet. When I am controlling say 10 parameters, mixing in reason, I have had the box reset itself, but not all the time. Has anyone experienced the same problem?

I have been running my midibox plus with Reason 2.0. for awhile, I haven't had any problems yet with it. I just basically set each knob with a different controller number and channel with a different synth or program, and use the midi learn of Reason. Works great. -Sephult

Thank you so much Thorsten! You pretty much summed up most of my questions regarding the handling of the SID chip. I am so ready to begin my workstation, and have already scavenged up (7) 6581 SID chips for it. I am looking forward to the Phat mode you have mentioned, I wouldn't mind experimenting with 16 chips. I will keep you posted with my project once I begin, and send you some photos when I get my design worked out. Thanks again, Awesome job, with the site reworking, and I am always looking forward to your future upgrades and projects. _Sephult

Hello Thorsten- I'd like to say that you have been so good to the public, for sharing your concepts, and finished work. I have been putting off my midibox for awhile trying to catch up with all these new designs, and circuits. I was wondering if this would be possible. By keeping the control surface minimal for a rack space, couldn't you implement a second PIC chip, say with 10 rotary encoders on the front panel to control different parameters that can be selectable by different banks. If so it would allow 160, different settings to be selectable. Ex. All OSC 1 control settings on bank one, OSC 2 on bank two? By doing this wouldn't you be able to keep the SID information such as patches seperate from the actual hardware setup that is going to control the SID chip? Maybe a way to update the knob values on the PIC control surface by sending patch information from the SID PIC, to the hardware surface would work? I'd like to say thanks again for all your inspiration Thorsten!!! _Sephult

Kieran- I know that you were probably searching an answer from Thorsten, but I thought I could help you with a couple ideas on what you have asked about. I have been working on an idea similar to yours for awhile. I was going to incorporate a bunch of circuitry and I had ran into the problem of size matters due to the millions of knobs Thorsten has let us use for these midi boxes!!! :) The best solution I could think of for switching purposes was to incorporate 5v relays for the switching. Unless you could find a Million Pole, Million Throw switch, that is about the only choice that I could think of for switching purposes. When I get my schematics done for a switching circuit, I will be sending it to Thorsten and hopefully others can use it like you. -Sephult

Hello- The push-button triggers are assignable just like the potentiomenters. Yes they do send just like the pots, but only in two states. The 16 banks are the different configurations you have set up on your midi box. Ex. One bank has been taught for a setup for a mixing board, and the second bank could have completely different controller numbers assigned to each pot for a different synthesizer. It is like calling up different programs on a keyboard, or synth module.

Hello Again! I was wondering if the introduction of the PIC18F would help to decrease latency when using it in the midi merger. If so wouldn't the merger be the best option for interconnection of multiple processors to one midi output? (after removing optoisolators)
