There might also be something useful in TK's MIOS TV project

Wouldn't the MBHP LTC module do for this? It's a nice plan :) I can see how taking advantage of the full screen would be good. I'm assuming by using the PalmOrb code as a starting point, the Palm would still be emulating an MO display, but with an arbitrary size to use the full screen width and height. Or is this more of a jumping off point, and you plan to create a custom Palm serial LCD software controller? Any thoughts on emulating any of the other existing LCD types, like HD44780? Using the touchscreen or buttons on the Palm to emulate MIDIbox button presses would be somewhat cool too.

I tried to put an LFO on my Stradivarius once but I never could find the damn CV in.

I really think the simplest solution is going to be a free or cheap second-hand Pentium 1 era laptop with some DOS, Win or Linux MIDI routing software on it. Or possibly an embedded x86 single board computer inside the case, or hanging off the back. I strongly suspect that the Legacy speaks to the Korg software in some non-standard ways, and it might be hard to do what you want even in software, in which case you're back to the idea of re-wiring every single control to a new custom MIDIbox. For those who haven't seen the Legacy, there's more to it than just a keyboard. There are knobs and patch points (plugs and cables) on the control surface that emulate a Korg MS-20 analogue synth, and speak to the matching software synth in the computer. On the other hand, is there info in the manual about controlling the software from a standard MIDI controller? Is it possible to map -every- function of the Legacy keyboard to a standard MIDI message? If so you might be in luck, if you can gain access to and decode the raw data from the internal hardware.

Well' date=' my Simmons drum module for example expects +7V for a full velocity trigger at the 5 pin sequencer input. It will trigger at 5V, but at a reduced velocity. My Roland System 100 from memory expects +12V or +15V. Other modules, especially home made or cloned ones, may expect a higher voltage too. It might also be useful for controlling high-current lights or LEDs in a MIDI controlled light show, or for those in the MIDIfication forum working on old organs etc. I also had this slightly insane idea for implementing velocity/accent in a drum sequencer by boosting the voltage to all the pins simultaneously. I think this chip could handle that.

Man that thing could hurt

11 minutes, stryd, must be a new record ;)

$1.95 ... serial in ... up to 50 volts out on 8 pins at 150mA continuous/500mA peak ... Sparkfun strikes again

Need more than +5V to trigger or power something? This little beauty from Sparkfun takes serial commands and can spit out up to 50 volts at 150mA continuous or 500mA spike. I'm cataloguing other intriguing parts on the Drumstuff wiki page

RGB LED matrix w/ SPI serial controller backpack $59.95 RG matrix w/ backpack $34.95 wait .... there's an onboard microcontroller' date=' and it's reprogrammable? * brain explodes you realise what this means?? it's LED SENSOR TIME!!

/wets self, puts thread on notify. If they're an inch or less, that's 16 to a 19" rack with room to spare... half an inch gets you 32.... I'm guessing that's for the actual switching component.

The CEM and SSM chips from old synths are analogue - all analogue oscillators, filters etc, just etched in silicon. Someone had a aproject around here to make a synth using a few PICs, one for oscillator, one for filter etc. To emulate analogue in software (which is what a PIC would do) might be beyond a PIC if you want to do it all on one PIC,

Nice work!

How much are you asking? And where are you?

Well done mess :D I'm adding a link to here from the Drumstuff page. What project are you building this into?

You might find some helpful clues linked from the DrumStuff wiki page.

Oops. I just saw "VCR" and assumed that's what it was, couldn't be bothered downloading the PDFs to check.

Except timofonic is asking about VGA, and this app outputs PAL video

Everybody understands the difference between a USB host and a USB device, right?

Found an interesting page: CAG: Cloned Analogue Gear A bunch of synth and effects schematics and PCBs. Has some voltage controlled resistors, envelope gens, etc. All PDFs

S-L-O-W and good luck getting serial MIDI to work

Pfffff

As far as I know, you need at least Java 1.4 for the MIDI stuff, and that's only available for OS X

Shuffle as implemented in the TRs and Thorsten's code though is well within the capabilites of a PIC, and though sure, it doesn't sound like a human drummer, it does at least allow you to add some robotic swing to a groove. I use it all the time on my 707, and it definitely brings da funk to town.
