Thank you TK!!!

Hi: I have a MIDIbox64 I didn't use for a while. It have 32 pots, 28 buttons, 16 leds and a 2x16 display. I remember reading that is possible to load the firmware of the Sequencer V2 into it, but I can't find the info now. Is it just a matter of editing setup_mbseq_vintage.asm? Thank you.

Hi Thorsten: Problem solved. The clock is working great!!! Thank you very much!!!

Thanks a lot Thorsten!!! I will try it in next few days and report back. Just a question: I always used MPASM to make the HEX file (I have to mod some things in the main ASM), can I still use it?

I have a Juno-106, a Juno-1 and a Matrix-1000, but no experience with MIOS 32, I have make a board, or two... Thank you.

Hi Thorsten: Did you look at the sync problem? I tried to look at the code but my programing skills are almost null. Thank you.

Thank you Thorsten!!! Hope it can be solved :)

Hi: Recently I'm using more the clock output of the MIDIbox CV (firmware ver. 1.2a), and noted an anoying behaviour. My sequencer (SONAR) is sending MIDI Clock all the time (even when stopped), and MIDIbox CV y synced all the time, so is outputting Clock signal all the time, that's OK, when I hit start in my sequencer, the MIDIbox CV keeps outputting Clock, but not sync the division to the start of the sequencer. Let's say I configured the Clock of the MIDIbox to 24/12 ppqn, when I start the sequencer most times the clock is shifted from the the tempo of the sequencer. The shift could be anything between 1 ppqn and the division I set in the MIDIbox configuration (1/8 note in my example). How could I reset the counter in the MIDIbox CV when a MIDI start message arrives? Thank you.

Hi: Some time ago I finished my MIDIbox CV, but the LCD Backlight never was very bright, the LCD is Winstar WH1602B, but the color scheme is not the same as in the Winstar site, mine is blue background with white characters. I used another one for other project and worked OK, but this one is barely readable with this dimmed out backlight. Finally I decided to add one or two white LEDS at each side of the LCD, and I'm wondering wich is the better way to power them. Can I simply connect the LEDS directly to the pins B- & B+ of the CORE V3 (PIC based), just in parallel with the actual backlight, and without any current limiting resistors? or is it better to connect them directly to 5V with some current limiting resistors? Thank you.

Hi all: I finally did the acetone bath to some 80017a. I took the coat away of 3 chips using acetone and 2 of them worked OK. The third one, worked too, but not quite right, the VCA worked, but the VCF behaves strange, the resonance have little effect and the cuttoff have a non linear response (very weird). Anyway 2 of 3 is a good number. Now I have 5 coated working voices in my Juno, and 2 uncoated working voice for a total of 7, this left me with a spare voice. I will start to decoat the working voices one by one to prevent them from failing in the future, and if something goes wrong I will stop decoating and still having 6 working voices.

Well actually I don't have one that complex. I use the controller sliders of ERA and draw some basic waveforms, then if I want to somooth out the steps I use the Slew Rate of the MB CV or a portamento module. Sometimes I use a plugin, I can't remember the name, but most of the time I use the envelopes of the DAW, I simple make an empty clip of 1 or 2 bars then I draw a waveform with the envelope of the controller I want, then copy the clip (with the envelope) over and over.

Yes, the MIDI jacks are on the back of the modular, as I will keep it connected always, I tought it will be better to left them there. Also the MIDI is chained internally to other module (Quantix-8). I built a standalone MIDIbox SID, a modular version is not im my plans for now, but...

Hi: The MIDIbox CV is acting as an interface between my computer and the modular synth, so I can sequence it from my software sequencer or I can play it from any of my MIDI keyboards. Also I'm using the extra CV outs to send pitch wheel and controllers from my software sequencer and keyboard, and software generated LFOs and envelopes. Also I'm using the clock out to trigger things (like ADSRs).

Hi: I built a TR-9090 (an clone of the TR-909) and played several analog drum machines, and all behaves the same. That's the cool thing about analog, if you want a steady repetitive sound go for samples.

I can confirm that. Mine is running at -15 +15 V.

Glad you liked it!!! The MIDIbox CV with the AOUT works great!!!

Hi: Over the weekend I did a little track I've posted at the electro-music forum in this thread: http://www.electro-music.com/forum/topic-33556.html Hope you like it.

Hi: I'm proud of having another MIDIbox of the Week. Thank you. Also I have some pictures of the modular featuring the MIDIbox CV.

Hi: Some weeks ago I finished my MIDIbox CV, it's working great. I used a AOUT module and powered with +15-15V without any modification. I have a sugestion to make: I'm unlikely going to use 8 voices with my modular, most probably between 2 and 4, and the left CV outs will be assigned to CC. That leaves me with 4 to 6 unused gate outs. Maybe in a future version could be implemented a sub-menu to assign those gate outs to something (ej: midi note on to trigger drum voices, or CC switches like portamento on/off). Thanks TK for this great project!!! Now some picture: MIDIbox CV Front.JPG MIDIbox CV Back.JPG Modules 1.JPG MIDIbox CV Front.JPG MIDIbox CV Back.JPG Modules 1.JPG

Hi: I didn't played much with the Yusynth VCOs yet. Two of them tracks well for 7 octaves and the third a little bit more than 8. They sound very good. I finishing the cabinet now, so when I take the modules off the carboard box and put them in the cabinet, I will do some recordings.

Hi: Here is a picture of some modules I finished of my DIY modular synth, incluiding a MIDIbox CV. I'm working on the cabinet now. I will post better pics of the MIDIbox CV soon. Modules 1.JPG Modules 1.JPG

I'll leave it as it is, then. Thank you TK

Hi: I just finished my MIDIbox CV and is working great, I will use it to control my DIY modular. I used the AOUT (MAX525s) and powered it from +15-15V, also used the J5 of the CORE as gate outs. These outs are took directly from the PIC to the jacks without any protection, and I know that every time I will plug a patch it will short briefly the PIC outs to ground. I don't know if the PIC could take this stress or if it is better to protect the outs. If protection is the way to go, do you think that a 100 ohms resitor in serie with the outs is enough? Thank you.

Haha, great you can, I can´t. I was just trying to show how simple is to modify the original MB64, and use it to control multiple synhs, and still use it as a midi controller. By the way, I heard somebody mentioned tweaking the Juno-1, well... it can´t be done. If you want to edit a patch is OK. But if you want to control various parameters in real time while your sequencer is running, the timing becomes totally messed up. I usually use the MB64 for some speedy patch edit (for in deep edition I go for software, specially with the Matrix), if I want to tweak in realtime, sysex is too slow, so I go for CC, sadly the Juno can´t do CC so I end assigning the filter cutoff to aftertouch, and use the MB64 to send aftertouch messages. Also some parameters of the Juno can´t be controlled in full range by sysex (I think is a bug in the Juno), for example you can´t assign the maximum range of the aftertouch to the filter, you have to do it from the frontpanel. I knew all this before starting to build my MB64, so instead of trying to clone the PG-300 just built a flexible MIDI controller.

Hi: I built a MB64 with 32 knobs and 24 buttons, and i´m using it to control my Juno-1 and Matrix-1000. I modified the MB64 code to include some sysex of both synths, my plan was add more but I´m happy with it as is by now.
