There is a separate registration to the MIDIBox Wiki as it resides on another server. It has been closed since spambots were wrecking it. New users should either contact the admins like SmashTV, or maybe you could just tell kristal= what you want in a PM.

If I could pony up the cash at the moment I'd buy the whole shebang for distribution... It would be nice to toy with a couple :)
-
Good one! Hats off!
Y U hate on supersaw? It's no worse that drippedy drops, risers, reece sounds or wobble :tongue:

Can't you try a Schmitt trigger in order to clean up the pulses a little? The problem is that it might do something funny with the signal when it's ringing too...
-
Ahh, saw that after a little looking. I'd attack the shunt in case it's not doing its thing. Chances are that a non-pro multimeter is worse than the shunt though. Looking at the module design it went from the *censored* LM324, an op-amp that has nothing going for it unless you want a rotten vintage band-limited sound to a TL-074. A 084 might be better, or you could try another low-offset opamp using that common pinning.

Some of the pots are for the interval, you want 1.00V/Oct, some pots should take care of the offset. Normally this is done so that you try to dial in one or two octaves on the interval, adjust offset, move to higher octaves etc. Just like in Maths you're doing a linear curve fit here. It's an iterative process. If everything has been soldered correctly it should be relatively easy to get at least 5 octaves that are very exact and 7 octaves that are exact to okay.
That said, only the bipolar mode of the AoutNG let's you adjust both gain and offset with trimmers. It says on the AoutNG page how this calibration is done. One thing to try is to swap TL074 to TL084 since the latter is optimized for lower offset voltage in the opamps. However, these days with modern semiconductor manufacturing the difference should be very small.
Some products and projects will use manual calibration to get as close to a perfect curve as possible, then add 1-3 points per octave in order to build a linearization table to get around small flaws and deviations from the ideal curve.

The TA12 series of switch caps work just as well. Problem is that Mouser only have a few of them in Black at the time of writing, and some 800 in gray. Digi-Key don't seem to carry these.

Meanwhile, survival tip of the day: If the PCB has thru-plated holes I'll just solder if from the top :O
This saves lots of time. Then it's time to turn it over for some snipping. Any missed resistors or diodes will fall out, much merriment! Of course, once those things are out of the way there's only so much that can be done upside down.

Hmm, this is relevant to my interests :D
I have enough hardware synths to warrant getting some of these as I kind of sort of should get a MIDI patch bay at any rate. The old Mac G5 tower runs some old-school Mac PPC software like SoundDiver, Galaxy and such, the PC runs MIDIquest and separate editors for the XV-5080 and a few more. The i7 MBP runs Cntrl, the editor for the Radias, MIDIbox Studio and what not. Something like this would help me. This is even before I think about the iPad and those editors and things...
I'd be happy to help out testing this. Well done!
-
Where at more exactly? I could slap one together for you if the building part is the problem. PM me :)
-
This demo - it's awesome! BTW, Newhaven has updated their OLED data sheet so it's now possible to correlate the PCB drawings with the actual OLED PCB too in case you need to patch it...
I need to dig out the old MB-6582 and see if I can re-enable the OLED and get it working :D It's been resting for far too long while I've been diverted to other DIY thingies. Exciting times ahead!

@Shuriken: Hope that's OK with the powers that be. They're made in Estonia by a mr Adrian Hallik. I'm unsure of the exact relationship, but I think he's employed at a metal shop with a screen printer. I suggest you register over at Mutable and give a shout out to Adrian.

The Sonic Potions plastic case (acryl/Plexiglas) is cut by the same nice gentleman in Germany who does the plastic Mutable Instruments cases for Shruthi, Anushri and the Ambika. You could always try to contact him for other one-offs, but his business revolves around non-synth stuff most days. Ponoko/Formulor or something like Seedstudio might be more suited for prototypes or for cutting down on shipping depending on your continent.
Some other DIY synths like the PreenFM 2 and the Audiothingies P6 also use similar cases. Plus the Peter Kvitek devices like the MidiALF and such. Somehow the Sammich SID begat the Sammich FM that inspired Mutable who then propagated across :D
If you feel like spending more, those projects mentioned are also available with screen-printed sheet metal boxes with wooden sides. That would probably cost a lot or end in tears for a one-off proto, but it can be done.

Yet another nice-sounding song :D Well done!

Not everything is stupid expensive in France! This though was a bit rich...
-
Not to complain, but is it hand-assembled by Marie Antoinette working for LMVH? Someone needs to get a grip :)

Wow! That looks very professional and sturdy. Well done!

:D
I saw that Newhaven had revised their datasheets for the 4x20 OLEDs so that the actual jumper section looks like it does on the display. That might be a great way to get one working in 8-bit or 4-bit mode as you see fit...
With some luck things will be more calm round here so that I could investigate a bit.
-
I think that Scifo and Schrab were in luck with their builds. It would be nice to get a blow-by-blow write up on how to get an OLED rolling. I got frustrated and left the OLED alone to pursue some other DIY projects for the longest.

Nice song and vid as always! Thanks for sharing it :)

Ask in the flea market section/WTB or add yourself to the list for the next GM5 IC bulk order. SmashTV handles the Wiki registrations.

All that hardware - bridged. What's not to like? Lemur or iPad remote edit/control over all devices - check. Less latency issues - check. Big fat physical MIDIbox controllers for the gear - yup. This will become handy for me :)

Well done! 'Twas a nice listen this fine evening :)

Nice n'dreamy! Yes, it's definitely the Hawkeye sound :) There's something's really tranquil about those flying sequences too. Keep it up!
