i see, that has to be the PSU. thanks for your comment!

I bet there is no possibility to use the 64240C display for the MBLC, cause other members surely would already have found it... One of them is only about 30 EUR. That would be way too easy........

Hello, dunno if this was covered yet, but I didn't find results for this GLCD controller: ST7565P is there a chance it is compatible to the KS0108? The ST7565P is used by the Displaytech 64240C I attached the datasheet. (I am still looking for a 240x64 GLCD for a Midibox LC. Unfortunately the Diaplaytech 64240A is nowhere to be found, seems since years after i have read all the forum postings about that.) 0900766b807ed6c1.pdf 0900766b807ed6c1.pdf

hi, i am looking for one of those too. the "legendary" displaytech 64240A would be perfect.

sorry, i didn't check the voltages because i removed the yac to just solder it again. now the opl3 module doesn't make a sound, except that the yac and the amps get hot. so i guess i still have a short on the pcb.

silly question: is it possible to connect 8 normal faders instead of 8 motorfaders? (that means leaving the whole motor-touch-automation stuff out)

Alright, I will check the voltages again tonight!

I dont' think that my case is normal. Everything sounds distorted. But anyway, the YAC and the amps get hot and now I hear nothing! Gonna buy another soundcard.

I got the voltages of the amps straight to +13V/-11V. Is it acceptable or could there still be an error somewhere?

Ya I did. Or... actually I connected the +5V and ground from the PSU directly to the +5V input and ground on the OPL3. From there +5v and ground to the core, and to ground of the +/-12V on the OPL3, and to ... umm maybe the story is too hard to follow. Whatever, maybe I just check all connections tomorrow[move]move[/move]

Hmm, that's not normal. The two amps after the YAC are at ca. +9V and -15V. The third amp next to the outputs is even at ca. +4V and -20V! The error has to be between the +/-12V/ground power pins and the amps i guess. Maybe I soldered some cap wrong? I will check the voltages later.

www.schaeffer-ag.de is the company that made the original frontpanel at least fot the midibox fm i think. they're in germany and they have downloadable software to create your frontpanel

???? ??????????

Thanks for your answer, Voltages of the PSU are exactly +12V / -12V / +5V. I read somewhere that the transformer for the DIY-PSU should have a few Volts more than 12V output, should the the wallwart be the same? I will check voltages of the amps as soon as I am outta work.

Hi, sorry to ask again, but I always have some crackling when playing the MBFM. No unusual background noise when no note is playing though. I am using a ebay-ed wallwart with +/- 12V (250 mA each) and 5V (1A) outputs. Too much? Or is it normal due to OPL3 limitations?

It is not the FM because that would mean very limited possibilities. Only because "FM" Synths are actually doing PM (phase modulation), for example feedback loops are possible. With FM, the OP would cancel itself out at the point any feedback is added, resulting in no sound at all. There is lots of info on (by far not only) that in The Csound Book.

For those who like to have some basic info how to stack and tune your C's and M's: www.xs4all.nl/~galink/sy-prog.pdf The paper has examples for the Yamaha SY-77, including RCM. We don't have RCM, and we don't need it. Also we don't need the SY-77's 6 operators, do we? I own an SY-77 and yet prefer my MBFM. What a coincidence, the name used to work at my university...

My main interest is having a display and switching patches on the unit. That should be easy with a simple SID-like CS.

It does! I think so too. It is user-friendly, for beginners and experts.

yes, roughly.

Actually, it is not bad to experiment with the Remote SL mapping, but now I am adding a selection of Mackie control buttons, and up to 4 control surface locks. (That means, you can lock groups of 8 pots/faders/encoders each to 4 devices or plugins, on the fly. Of course you will have to use a MIDI controller with 32 pots/faders/encoders if you want to use all 4 locks. Example: you have 32 pots. You lock 8 to the Beat Repeat in your drum track, 8 to the fx plugin in your master track, and 16 to 2 soft synths. Five minutes later you played enough with the Beat Repeats and lock the first pot group to your Filter Rack... I think you know what I mean.) Also, I make the possibility to cut down on required buttons by combining the select/rec and the mute/solo buttons. Pity the LEDs quite can't deal with that, unless you have two-color LEDs.

Hi, I had the idea to check if my 'ultra-versatile' and 'timelessly-reusable' MIDIbox 64 could imitate the extended instant mapping support the Remote SL Controller by Novation does in Ableton Live. There already was a post about the Remote SL MIDI I/O configuration in this forum, but seemingly with no further activity. So I decided to create a new topic about what I call Remote SL Extended Instant Mapping, REIM. The REIM is actually pretty useful, much like half of a Mackie Universal Control: switching between banks of 8 tracks each switching between control over volume/pan/sends in those banks locking control surface to devices or plugins mute/arm each track easily transport control macro functions and up to 8 banks of device controls (e.g. modify each slot in Impulse using its 8 macro banks Actually any half-way equipped MIDI controller could imitate the MIDI config of the Remote SL, so TK's MIDIbox could easily do it twice! (as you will see later, it basically does.) I found out all MIDI sent by the Remote SL, actually without ever having seen or touched one. Once again the user-friendly architechture and functionality of the MIDIbox project helped me with that. More info soon. I will create some PDFs to ease it all up. PS: I would appreciate some help about LED lighting later. I would like to get the LEDs working as they would on the Remote SL. (Track mute/record, volume/pan/sends buttons and so on)

Got the MIDI I/O? I did it too, it is quite easy to imitate ableton live instant mapping with any midibox that has knobs, buttons and sends midi.

what is live ccs and how you want to whack them? please explain for non-native speakers. ;)

That is a very good point! I would like to get something like that too. So if I should happen to find something, I'll tell you.
