Very nice! I love it! Luke

I see this in rc30 as well. Luke

Awesome! I was just working on this the other day. Thank you! Luke

Nice work TK! Sounds great, you are certainly progressing from earlier demos! Luke

Totally understand. I'm just honestly curious. I was left feeling quite the same way when I finished mine, but now that I have had it and used it for a month I'm really liking it. Simply for the sound quality alone it's worth it in my opinion. I have been using mine as an external effect from ableton. The real time mode has been the most fun for me so far. Luke

Maybe post the features you would like to see on his forum. I believe there will be another firmware release. Just curious, what features would you add to make it 1000x better?

I've built one of these up and I have to say it's an amazing project. I love it. So crispy and crunchy. I plan to add one of Seppo's 2044 setups to it. I've run it through the one I have on my MB6582 and it sound beautiful. It has an effect mode that lets it just process incoming audio in real time. Really fun stuff and a very easy build. Luke

Same here, got mine last week sometime. Thanks! Luke

The psu seems to always show +5v, that's the weird part. Even when the base pcb is showing +2v, the pins of the psu are showing +5v. So I think something is going bad on the base pcb, but I'm not sure. I have a desktop power supply that I'm going to try to see if its the psu before I do anything to the MB. Another weird thing is that once it starts, it never flakes out on me. Works just fine. It's only an issue when first starting the synth. Think it could be a bad cap or something maybe? I tried removing all pics and sids except on core one and I got the same kinda behavior as far as I could tell. But I will certainly try that again. What makes it kinda tricky to debug is that once I've been using it for a while the problem seems to go away. I will try using my bench supply to eliminate that as a possibility. This is great news, I was originally hoping I could just use the included midi io but wasn't sure I would be able to since there are no pins for it on the pcb. I will give this a shot over the weekend. Yes it is, and this is exactly what I had hope to be able to do. I am currently working building an additional enclosure that has the same width and height dimension as the pt10 case but thinner and not slanted so I can sit the MB6582 on top of it and just connect it via the expansion port. The application that I wrote for the ESX is currently running on a 4685, so this should work out perfectly. I'll give a shot and let you all know how it goes. I'm sure I'll run into something I'll need help with. Thanks, Luke

I finished my MB6582 just about a year ago and have been using it off and on since, I've always liked the synth. I have finally gotten around to getting an aout_ng and an ssm2044 board put together. I am just completely floored by how amazing this setup is. I have owned and had access to many synths over the years and this is right there at the very top of the list in my opinion. The only thing I have ever heard that was as ballsy as this setup is a mini. It's increadibly warm and organic, it never tires my ears out. Before I just liked the synth, now I am fully in love. I just wanted to say thanks again to TK, Wilba, Seppoman, and everyone else who has helped me and contributed to this project. You guys should be very very proud. So now for a question. Somewhat recently I have been running into a problem. When I first turn on the synth often times it doesn't start. The power led will light up, but not fully, its dim. Some times it will eventually turn itself on, but more often if I leave the power switch turned on and unplug the psu and replug it in to the power jack on the synth once or twice it will start up. I have taken some measurements when the power is on and the led is dim. I am only getting about 2v at any of the 5v pins on the base pcb. A lot of the time the synth will actually start up as a result of me taking a measurement. Once the pic boots up the readings are normal everywhere a nice solid 5v. Usually after I have been using the synth for a while it will turn off and on normally. My first thoughts are that the psu is bad. Its an original c64 psu that supplies 9v and 5v. This could very well be the problem, but when I take a measurement from the pins on the power jack I'm getting around 5v usually a little higher, but still only getting around 2v on any of the 5v pins. I've looked for shorts and re-flowed most of the solder joints, that's not to say I didn't miss something. Any suggestions on what I should replace first or where I should look? Second question. I would like to use one of the cores on the base pcb to run a different application some of the time. I have an app that does some midi processing for my ESX, and it would be cool if I could use one of the cores to do this when I don't need it as a SID engine. So can I just upload the hex to the core I want to use? I know there is only one optocuplor and one set of midi io, would it be possible to use an IIC module to get a set of midi io to one of the slave cores and still have the main midi io for the other 3 cores? Thanks again, Luke

I ended up getting some monome buttons. The seeed buttons are fine, but they are clicky as hell. If that doesn't bother you they are great. This is not my project but here are some pictures of what they look like. http://www.seeedstudio.com/blog/?p=176 Luke

Below are the parts that I ordered from Mouser. I built my GM5 last night and it works like a charm. Though these parts should probably be verified, they do for sure work.

Ill take it if its still available. Thanks, Luke

Awesome. Two please! Thanks, Luke

Quick update on this. I have gotten this to work quite well. I was able to reduce 8 note on messages to set a row of 8 LEDs to 1 note on message. I will soon release the c code and a small max patch that does the transform. I was going to use NRPNs for this, but that would only reduce the messages being sent from 8 to 4 rather than 8 to 1. Its setup so you can easily choose the type of midi message you would like to use. It works by rearranging the bits in a 3 byte midi message. This allows you to take the low bits from the 2nd and 3rd bytes to get the full 8 bit value to set all 8 LED's at once. That leaves the high bits from the 2nd and 3rd byte to set the command type and the row or col number. It's pretty simple and allows for more command types if needed. Comments appreciated! Thanks to everyone that gave advice and TK for the great platform! Thanks, Luke Here is the mapping using note on. midi note on message 9n 7F 7F 12 34 56 1: Command Type 2: Midi Channel 3: Command 4: Arg1 5: Arg2 6: Arg3 Command Types 9: Monome Command x: More command types can be added here.

Been following this, I hope to combine it with a simple sequencer and seppoman's ssm filter. Looks like a lot of fun. Luke

WOW! Nice work!

I'm in, need the same as above. Luke

Thanks Bugfight! Works very nicely. This is a much nicer solution than mine. I knew it would be possible with a little math. Luke

I got this to work, I'm sure it could be done in a better way though. I just used a couple arrays to map the notes and the rows and it works for now. Luke

Got the hardware working. What is the most efficient way to do this so that my rows go 0,1,2,3,4,5,6,7 instead of 0,2,4,6,1,3,5,7? Thanks, Luke

Great! Thanks Bugfight, Ill give it a try tomorrow. Luke

Anyone know if it's possible to use this code and schematic with single color leds by just leaving out the extra connections? Thanks, Luke

No problem, I thought the same thing when I finished mine. Hope you get the other issue sorted. Luke

Not sure about the first problem, but number 2 is just how it works. Leds only trail on the first core. Luke
