  1. No donation required! I put the code here: https://pastebin.com/i6g3chj6 Feel free to PM me with specific questions. I don't have schematics, but all the wiring info can be found with a simple google search for something like "arduino midi in". The box is a Hammond 1590BB2BK, which is just the black painted version of the 1590BB2. A full table of the different sizes can be found here: https://www.hammfg.com/electronics/small-case/diecast/1590 The box was the hardest part to find. It took some searching but I found one at Angela Instruments (angela.com). The joystick can be found at Adafruit.com (among other places): https://www.adafruit.com/product/3102
  2. It might be cool to make a box that has both! Another thought I had was to turn this into something with audio jacks rather than MIDI. I've read up on how real-time pitch shifting is done, and I think I could build it. It would basically be a "Whammy" pedal in a box, so you could use it on anything, like a clavinet or a rhodes. I could call it the "Clav in the High Castle" (get it? Castlebar?).
  3. I've actually thought about this. I think they would be cheap enough to manufacture, but I doubt there's really much of a market for something like this.
  4. Yea, the program is stored in memory. It's written in C, but the code is very simple. The whole program is only 145 lines, which includes a lot of extra junk like comments to myself. The Arduino libraries make it very simple to send and receive midi. For example, if you want to send a midi CC message for the mod wheel it looks like this: MIDI.sendControlChange(1,value,midiCh); It gets a little more complicated when you are reading the position of the analog joystick, but either way the code was the easiest part of the whole project.
  5. So my main gigging axe is my Crumar Mojo and I love it... but lately I've found myself being drawn back into synths and ended up buying a SH-01a for synthy sols and pad sounds at funk gigs. For the first couple gigs I brought along a midi controller on top of my Mojo so I could have pitch and mod wheels, but I really just wanted to be able to control the synth from the Mojo's top manual, and leave the controller at home. Aside from the obvious problem that the Mojo doesn't have pitch or mod control, there was another problem that the Mojo's upper manual sends on channel 1, but this channel is also used to send CC messages everytime you touch the drawbars! I can't disable the Mojo's CC midi output and I also can't disable the CC recognition on the Sh-01a! So I built this little midi joystick in a stomp box housing to solve both problems! The board inside is a Teensy 3.2 (similar to an arduino). The incoming midi gets filtered so no CC messages get passed to the synth, and the joystick is used to send pitch and mod commands. Here are some pics: Here's the inside Here's a view of the jacks in the back, power comes through the usb port And here's how it looks velcro'd down to the Mojo: My first gig with it is this Thursday in Berkely and I'm pretty stoked!
  6. Trying to figure how something like this could be a fault of the SS. Have you tested this with another amp/monitor? My first inclination would be to check the Mojo on something like this. I've never noticed this in my other amps. The only thing I can think of is that they all have 12" or 15" speakers, so... maybe that is causing it? I should double check with headphones. Either way, it's not that big of a deal cause I'll always have my Eden bass rig to handle those frequencies at my normal gigs, but I'm still puzzled by it.
  7. I finally got a SSv3! Had the first gig with it last night using a Mojo, and had mixed results. Overall, it's a great product, and most of my observations are the common ones mentioned on this thread, but two other things stood out last night. The room was in a brewery, super reflective/echo-y, huge windows, no sound treatment anywhere. So keep in mind that the room was far from ideal. The first thing was that the volume of individual notes in the bottom 2 octaves were uneven. for example, Bb and Eb were the same volume, but the Db in between was almost inaudible. I noticed this even with the width at 0, so I'm confused how this could happen. The second thing was that it might not be loud enough for me. I was sitting about 6 ft away, so it had "room to bloom". When the band was really loud and I started to lose myself in the mix I had to really crank the volume to 4-5 o'clock and the amp started distorting! it was a weird sounding distortion though, maybe just a weird product of the room. I tried decreasing the Mojo volume, but that didn't help much, so I don't think the preamp was distorting. A related observation was that the volume of the EP sounds changed dramatically when I switched on/off a stereo effect. Not a terrible thing, but something I'm really gonna have to watch out for. Has anyone else noticed their SSv3 distorting at high volume?
  8. About the SS pedal idea, Aspen tried a version of this years ago, but it never took off. Probably for the best.
