Guest gadarby Posted August 21, 2004 Report Posted August 21, 2004 Hi all, Forgive me if this is an obvious question, but would it be possible to create a homemade equivalent to the roland PG200 using the ideas & concepts behind the midibox?Many thanksGareth Darby Quote

moebius Posted August 21, 2004 Report Posted August 21, 2004 And why not?! ;)The biggest problem is that you need to know protocol specification of the PG-200.. I haven't seen any information on that.. Of course It could be reverse engineered, but then you would need a working unit, a logic analyzer and patience to extract and analyze data streams..After that it would be pretty easy to adapt something like MB64 to simulate PG-200..Bye, Moebiusp.s. It's a secret (as long as I'm searching for cheap MKS-30 ;D), but JX-3P/MKS-30 Rock! Which one do you have?! Quote

Guest gadarby Posted August 21, 2004 Report Posted August 21, 2004 Moebius I have an alpha junp 2 which I am told the pg200 will work with. I did consider a jx-3p a while ago but for some reason never got round to purchasing one.I was under the impression that the PG200 would be a midi controller which just gave users a realtime control surface to their roland synths. Would the protocol spec just be the CC's for the relevant parts of the synth?Gareth Quote

moebius Posted August 22, 2004 Report Posted August 22, 2004 Oh,That's PG-300, and yes it's a midi device.It doesn't send CC's but SysEx to control parameters, you can find manual for it (and MKS-50, rack version of alphajuno) from: http://www1.ftg.co.uk/studio/mks/index.cfm?mks=50And just the SysEx implementation:http://machines.hyperreal.org/manufacturers/Roland/Juno/info/Alpha-Juno.sysex.txtI think that using meta events, pots and buttons can be used to send out SysEx, but I really don't know how it's done. Check out source files, as I think Thorsten has used it to control some Yamaha AN1x parameters.Bye, Moebius Quote

Steven_C Posted September 9, 2004 Report Posted September 9, 2004 The PG200 has a funny connector that it links to the jx3p/MKS30 with. I've also heard that it isn't possible to use the PG200 at the same time as midi, though I'm not sure how true that is. Does anyone know if it is possible to make your own ROM chips to get the velocity upgrade? Actually, maybe it is possible to get them direct from roland....I've been thinking of buying a jx3p...

arumblack Posted September 10, 2004 Report Posted September 10, 2004 Of course if you had the contents of the rom you should be able to burn one. Where to get the contents? I don't really know, perhaps there is a way to read the contents from one rom to be burnt to new one's? Or maybe Roland has , and will give away, that data.I have been wondering the same thing as i need roms for a korg dw8000....... Quote

moebius Posted September 10, 2004 Report Posted September 10, 2004 Hi, Steven_CAs far as I remember, It isn't possible to use MIDI/PG-200 same time with JX-3P, but with MKS-30 it is... Sad isn't it :)I sold my JX-3P years ago.. when I wanted to get rid of excess keyboards on my setup. It's good for some 2 DCO basses, strings and strange osc sync klangs.It's a piece of cake to PROM new firmware to EPROMS, but where to get dump of firmware?!Anyway.. Steven and Arumblack, check www.analog.no.. could be useful..Bye, Moebius Quote

Guest nickca Posted September 11, 2004 Report Posted September 11, 2004 It should be possible - I've configured my MB64 to emulate an MPG80, the programmer for the MKS80, which is basically the same thing with different SysEx. Just edit mb64_meta.inc and replace the AN1x SysEx, then set the MB up to call the right meta events.Here's my modified mb64_meta.inc. Quote

Guest nickca Posted September 11, 2004 Report Posted September 11, 2004 Also, AFAIK this is true for all the Roland programmers - they send SysEx over standard MIDI, the only thing special about them is the weird cable. Quote

el-bee Posted April 3, 2006 Report Posted April 3, 2006 Came across this and ordered one for my JX-3P immediately..http://organix.inque.org/jx3pexpansionkit/Not a direct PG200 replacement, but something that'll make the good ol' 3P understand Midibox.. ;) Quote
DrBunsen Posted April 15, 2006 Report Posted April 15, 2006 Slightly off-topic: I have an MKS-7 - no external hardware editor was ever made. Luckily it's all editable with sysex, but it loses all user patches on power-down. I dream of a MIDIbox patch editor/librarian for it, with random patch generation... Quote
stryd_one Posted April 15, 2006 Report Posted April 15, 2006 Hey did you win that on eBay recently? :)Man that controller is absolutely do-able. You could make a function to send the patches when it powers on too :) Quote
DrBunsen Posted April 15, 2006 Report Posted April 15, 2006 No, bought it about four or five years ago from a music shop in Brisbane over the web. $200. Unfortunately the idiot sent it to me in one layer of cardboard made out of two boxes sticky-taped together, and no padding of any kind. When it got here, two of the DCOs were funky. I shelved it and never got back to it. They could just be loose in their sockets, or they could need replacing. $$$ Quote
moebius Posted April 15, 2006 Report Posted April 15, 2006 "Doctor Doctor.."Lemme take that limited piece of **** out of your hands.. ;D or then again: Midibox64 modified to good edit layout in with custom meta events and in patch mode and Your MKS-7 RoXX! (MKS-7 has a single edit buffer for the sounds, this would dump patch as SysEx when changing "patch" on midibox.. I'm been wondering about hacking into this machine.. (if I had one) and do some HW/SW modifications.)Moebius/edit p.s. Just hope the problem is in the oscillators not on the filters - the oscillators are standard digital counter chips. Quote
