This interests me very much.

I love your UI. You've built a miniature Simmons SDS6 :D

And I realise of course the simpler solution is to just build an MB808

That makes perfect sense. I realise it's not a simple feature to add. Just out of curiosity, how much code space / CPU time is left over in the current BLM Core?

http://ucapps.de/midibox_seq_manual_blm.html What I'm talking about is integrating a percussion sequencer - however limited - into any space that might be left on the BLM Core itself.

Simple, feature reduced, stand-alone percussion sequencer running on the BLM's Core? To MIDI Out and/or DOUT triggers? (ie, like drum mode of MBSEQ, or the MB808)

Ah OK, thanks for the reply.

I don't know if this will help or not, but recently I have been researching USB Host MIDI on Android platform. I found a note on one software company's site that said a USB hub was needed that supports "Multi-Transaction Translator" (MTT or Multi-TT). This will allow multiple USB MIDI devices to connect via the hub to an Android host. I've found hubs with those magic words in their description for around $20 on ebay, so perhaps this is worth trying out?

I am so very impressed D: YES!! My Roland MKS7 can has user memory!! Now this brings an interesting thought to mind - if you hooked up some CV outputs you could have a patch memory programmer for an analog modular synth... One other thought - would it be possible to have a minimalist version with say two groups of [ 4 encoders + 1 OLED ] and a page/menu system to access different voice parameters?

Hey Wilba, I'd like to put myself down for one (possibly two) in the next batch, but I don't have edit privs on the wiki.

I'm down.

Hi Thorsten. Great stuff! I have been hunting all over for exactly this solution. I should have known to come check here first ^_^ I'm keen to try this out. A question or two if I may? Do you have any ideas why USB hubs are not working? You mentioned power issues before - have you (or anyone else) tried a powered hub? Or do you have any other thoughts about how that might be fixed? If not, then I might try another board with more than one USB port, like say the new Raspberry Pi Model B+. Granted, that will involve porting MIOS :/ but I think FreeRTOS runs on it already at least.

FreeRTOS has been ported :frantics: http://www.raspberrypi.org/phpBB3/viewtopic.php?f=72&t=22423

Pardon my thread necromancy: This guy has a USB MIDI control board and a bunch of control software (running under Max for Live) for the MegaDrive. http://little-scale.blogspot.com.au/search/label/sega%20mega%20drive%20%2F%20genesis It appears his first run of boards sold out already: http://little-scale.com/

Fixed that for ya :homestar:

Well now, this could be interesting: Unofficial Behringer Control Development Kit Device hardware: CPU: OKI ML671000* (ARM7) @ 12MHz 512k of flash memory 2MB of DRAM As the STM-Core is also ARM (although Cortex 3), is a MIOS port even slightly possible? NB: this is not a request. Just thought I'd list the project here for anyone interested. (Found via HackADay) * 32-bit ARM7TDMIâ„¢ CPU, DMA, serial, PWM, analog-to-digital, timers, internal RAM and external memory controller.

So has anyone bought one of these yet? Got reports on the button quality for example?

Fabulous work TK! I have one question: I have recently been looking at hardware MIDI out from the iPad/iPhone dock connector. In searching, I have found one commercial product, the MIDI Mobilizer from Line 6, one Apple-approved reference design hardware RS-232 port, and some DIY schematics for serial I/O. Is there any prospect of your app supporting hardware MIDI I/O direct from the iPad?

I hope he's using lead-free solder!

You need a heck of a lot more than just a "pinout" to do this. You need a controller board which will cost you around $100. And it has to be compatible with that exact screen, and have the right cable. Pretty much, it's not worth it. Yeah, that's what I'd do, until you can afford a larger/better resolution one.

C'est çi belle!!

Heh, well it's stumbling distance from my house. I'll probably come and check it out.

If you look at it as a cheap way to get a nice case, power supply, and 64 buttons, and build the rest in MIDIbox hardware, sure. I wouldn't count on anything else inside being reusable.

That's certainly what caught my eye :D I was all "meh" about the unit until I saw the pricetag - and then my Dremel started buzzing :P

An LCD display wouldn't hurt, for showing internal settings and such things as pitch transpose, MIDI channel, etc.
