video upload by synthpro

"Hey Guys, In this video, I go over a very cool little Oberheim OB-1 I have been working on between all my other projects. As you can see in this video, its a great playing little synth once more after being dead for many years.

This particular synth belongs to David Ewing who played with Brenda Lee for 30+ years so this synth also has some awesome history behind it.

Here is a link to Tauntek's page on the OB-1 for those interested or struggling with your own repairs: http://www.tauntek.com/OB1.htm

Roland Jupiter 6 With Tauntek Mod SN 280707

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

"- Outstanding cosmetic condition

- All functions work ( see embedded YouTube video for a quick playthrough )

- Includes Tauntek Mod, which offers loads of new features:

1) MIDI Sysex patch and patch preset save and restore - saves or restores entire tone RAM (all 48 patches and 31 patch presets) in one operation (tape save/load works as before)

2) MIDI CC parameter changes are now supported. Separate control of upper and lower voices in split mode for most parameters. (No CC's are transmitted)

Maximum rate for CC reception is two per 19 mSec period, which is approximately 105 CC's per second. If CC's are sent faster than this, some will be dropped.

3) Non-volatile storage of MIDI channel and user settings

4) User settings for the following:

a) Mod wheel CC destination can be any one of the following:

VCO mod by LFO1 amount
VCF cutoff mod by LFO1 amount
VCA mod by LFO1 amount
LFO1 rate
XMOD manual amount
Pulse width
VCF cutoff
VCF resonance
b) Arp can be clocked by MIDI instead of internal clock, with five divider settings

Can be configured to require Start/Stop, or just free-run

c) Factory patches and patch presets can be read from the EPROM instead of user patches in RAM.

(User patches are not changed)

d) "All notes off" MIDI messages sent by original code every time the last key was released can be disabled.

5) Arpeggiator "Down then up" mode has been changed to a random arpeggiator mode.

6) VCO waveform buttons now toggle, making it easier to enable multiple ones. They can all be turned off.

7) VCO sync can now be set to "both ways" although this doesn't seem particularly useful

As noted above, MIDI CC reception is now supported for controlling patch parameters."

Classic birds: Roland CR78 and Korg Mini Pops 7 MIDI flyover

video upload by ohm_studi_ohm

"Since these days I have on hand 2 classic - shall I write cult ? - drum machines that I retrofitted with MIDI interface it was very tempting to compare them in real time, playing the same thing. So I did !

The Korg MiniPops features the Tubbutec Unipulse interface (https://tubbutec.de/unipulse/) and the Roland CR-78 was upgraded with Tauntek MCU replacement (http://tauntek.com/CR78.htm). Bless these guys for everything they give to the synth community.
In this video I don't go deep into the MIDI functionality, i simply wanted to compare the raw sound of these 2 units. It would not be fair to compare them features wise. 10 years or more separate them and in many aspects the technology gap seems abysmal.
BUT they are more alike one can think at first.
What makes them very close is the nature, number and choice of drum sounds. The MP7 has 15 of them and the CR78 14. They have those sounds in common: Bass, Snare, Rimshot, High-Hat, Cymbal, Cowbell, Conga, Large Bongo, Small Bongo, Claves, Guiro, Tambourin.
The MP7 adds a second Snare sound (longer decay) whereas the CR78 has a second Tambourine sound (longer decay). The "maracas" on th CR78 can be interpreted as Cymbal 2 on the MP7.
Actually soundwise the big difference is the "Quijada" sound that's on the MP7 and is nowhere else to be found. Quite a jaw dropping sound it is !
So anyway i MIDI mapped the MP7s sounds to their respective CR78 ones as best possible so I now have 2 analog expanders rack :-)"

Seuential Circuits TOM with Tauntek TOM16 extansion

video upload by ohm_studi_ohm

"The Sequential TOM was already a great drum machine at the time it was released, with a lot of nice features, especially regarding MIDI implementation. You could play, record, synchronise the machine over MIDI and adjust sample direction, volume, pitch and pan of every sample either on the device or over MIDI, in real time and for every step ! That gives you lots of possible variations. Not many drum machines could could achive that at the time.

And now thanx to another amazing engineering by Tauntek you can have 16 kits in the instrument at all time, without the need to switch cartridges. And even more important: you can swap the internal kit samples as well as the cartridge ones, enabling for any combination of 2 kits you wish. This is impossible with cartridges or other upgrade available, and only possible thanx to Tauntek firmware. And that makes a huge difference. Note that you can only have 15 sounds at hand not 16. The 8th pad from the cartridge layer is always a trigger out message and won't trigger a sound, even if the loade kit has 8 sounds.

You can even make your own kits if you have access to an Eprom programmer.
Check Tauntek dedicated page for more info (http://www.tauntek.com/TOM16cart.htm)
This unit also had its RAM maxed out, expanding the internal 8k to 32k and thus bringing the stock 2,300 notes capacity to a whopping 10,400. And believe me you run very quickly out of memory if you make some complex patterns with different variations.

So here is the demo, i didn't make patterns demos for each of the 16 kits but you'll get the idea, and I didn't go too deep into external MIDI playing/programming but bare in mind you can record instrument tuning pitch, volume, pan and sample direction (reverse) for every instrument on every step.

Here is the timeline:
00:00 stock kit patterns
02:28 TR808 kit patterns
03:56 TR909 kit patterns
05:08 TR606 kit patterns
06:25 CR78 kit patterns
07:17 sound preview of all the kits included in the box
11:18 quick realtime patterns programming using external pads

Programming Crumar BIT99 with MIDI Controller

video upload by ohm_studi_ohm

"This synth is for sale. You can buy it directly (sales.ohmstudiohm@gmx.fr) for 1450 euros or buy it on eBay (https://www.ebay.com/itm/305202255093) or Reverb https://reverb.com/item/74807341) [pics captured here]



This is demo mainly to show how easy it is to program this synth thanks to the amazing work Bob Grieb (Tauntek) did by rewritting the firmware and enabling Midi Control Changes messages on this synth.

The only drawback (due to the hardware) is you have to retrigger a note for every change you make on a parameter, except for a few ones that a real time (resonance, DCO and LFO waveshape for instance). Just a minor annoyance compare to the original programming method (which is actually not the worse of that kind).

The BIT99 and BIT01 are very nice sounding and quite comprehensive 6 voice analog synth. They feature 2 DCOs with triangle, sawtooth and pulse waveform, in octave from 32 to 4 and you can combine the 3 waveforms on each oscillator. Dedicate ADSR enveloppes for filter and amp with velocity control, 2 LFOs, noise generator, split or stack possibilities etc

IMO they only lack a mixer for the 2 oscillators, LFO PWM (though you can control the PW with velocity) and a hi pass filter.

But the sound is very nice, I favore it over the Oberheim Matrix 6 for instance. It sits very easily in the mix. Build quality and keyboard are also of upper level."

Crumar BIT99 6 Voice Analog Polysynth

Note the seller made a video for another one posted here.

"The unit for sale works, plays and sounds exactly the same. (The Wersi Wersivoice unit in the demo can be added for an extra 200 euros)

6 voice analog polysynth from italy and the mid 80s.

The Crumar BIT99 was serviced:
- power supply electrolytic capacitors replaced
- firmware upgraded with Tauntek one: you can now easily control and program the synth with any midi controller using Control Change messages
- meticulously calibrated
- panel board and case fully dismantled, cleaned and polished
- loaded with factory set VOL 1 (Vol 2 sysex can be provided too)

It sounds, plays and looks awesome. It does has some light wear and scuffs but all in all it is in excellent condition.
I warranty the instrument at least for a year. Should there be a problem no need to ship the whole instrument back but only the board(s) needing repair. These synths are actually extremelly well built, by far the best italian synth i've seen (maybe safe for the Elka Synthex I never had a chance to lay my hands on). Quality and thickness of the metal and PCB are of japanese standards. Far better quality for instance than Moog from the 80s (Prodigy, Opus 3 etc) and by no comparison to the other (great sounding) italian Siel Opera 6."

Crumar Bit99 + Wersi Wersivoice

Note: Auction links are affiliate links for which the site may be compensated.
video upload by ohm_studi_ohm

"Quick demo of the Crumar BIT99 i fully serviced. In the frst part i flip through a few patches to let you hear how this one can sound, mainly for bass/lead/keyboards sounds. And in the second part I focus on pads and i run the synth through a custom built Wersi Wersivoice analog triple chorus. As you can hear i can turn the BIT99 into a great string machine and more.
Record with no other FX or treatment.
Pardon my playing, I'm better at servicing these instruments than playing them :-)"

via this auction

"Here is your chance to grab a unique combo in the form of 6 voice analog polysynth and a custom made BBD triple chorus ensemble effect.

The Crumar BIT99 was fully serviced:
- power supply electrolytic capacitors replaced
- voice board electrolytic capacitors replaced
- firmware upgraded with Tauntek one: you can now easily control and program the synth with any midi controller
- keyboard dismantled and contacts and bus bar cleaned
- meticulously calibrated
- panel board and case fully dismantled, cleaned and polished
- custom made real wood side end cheeks

It sounds, plays and looks awesome. It does has some wear and scuffs but it is in great condition.
STAND IS NOT INCLUDED.

The Wersivoice was custom built and is a great addition to any synth, analog or digital. It simply can turn anything into a great string machine, and more.
Very simple, no control: sound in sound out. There is a 3 positions switch with ON / MUTE / (true) BYPASS positions.
It runs directly from 230v.
Since it's DIY it doesn't look perfect."

Crumar Bit 01 demo with midi controller

video upload by ohm_studi_ohm

"Here is a demo of this italian 6 voice analog polysynth i'm selling (via this auction)
Unit was upgraded with the great Tauntek firmware and can now be controlled remotely over midi by Control Change with any controller.
In the demo I basically flip through the unit presets and edit some of them on the fly just to show how easy it is now to program this otherwise austere synth.

I didn't demo the bi-timbral feature of the rack. You can have 2 different presets, lower and upper, either layered ("double") or split. Lower and Upper parts can have their own audio output.
Preset from 76 to 99 are allocated for the performance presets and need to be dialed in (you can't use the + and - value switch to select those like I did on the video)."
