Elka Wilgamat, Oberheim DX and Powertran Transcendent 2000 in sync

video upload by ohm_studi_ohm

"Since I just finished adding DIN SYNC24 to my Elka Wilgamat I decided to hook it to the Arturia Keystep pro and further added an Oberheim DX and a Powertran Transcendent 2000 to the game.
Playing with the Wilgamat accompaniment part brought a known melody to my memory so temptation was high to follow this path...

The Transcendent can be seen in another video i made earlier this month. It was modded to add a sub oscillator and also to correct the peculiar CV/Gate it originally used in order to use it in a standard CV/gate environnment. It's now working fine when controlled externally as you can hear.

If you want to add sync to the Wilgamat there are 2 issues you need to adress:
- the unit needs 4ppq so unless you have a device capable of providing such a clock frequency you need to convert the more conventional 24ppq to 4ppq.
It's actually very easy to do by using a single 4018 chipset, which can divide by 6 the incoming frequency
- second issue is that the clock on the WIlgamat ask for negative pulses so you need to convert the positive pulses to negative ones. I used a single op amp to do that (TL071)"

rare birds: Powertran Transcendent 2000 with sub oscillator mod

video upload by ohm_studi_ohm

"Here is a Powertran Transcendent analog synth I just serviced.
I took the opportunity to make some modifications, mainly adding a sub oscillator circuit.
I used a simple 4024 chipset and routed the -1 and -2 octave outputs to the "noise" volume pot with a 3 positions switch so that I can chose either octave sub or the Noise generator as the source for that pot.
I also made modification to the CV and gate circuit which originally are not the common 1v/octave V-trigger kind.
Now it can be used with any standard CV / gate interface.
And last modification was a lighter one: adding a LFO rate blinking led.
Very nice synth, capable of quite a wide range of sound thanks to dual resonant filter mode (Low Pass / Band Pass), S+H, repeating enveloppe, PWM etc … and now with a sub oscillator :-)

PS: this synth is not unstable in pitch. If you look carrefully you'll notice there is a slight amount of lfo (saw) modulation applied to the OSC pitch almost all the time"

T2K-VCF Transcendent 2000 Eurorack Filter Adaptation by G-Storm Electro

video upload by gstormelectro

"Audio + Video by G-Storm Electro c. 2022

T2K-VCF is a Eurorack modular adaptation of the Powertran Transcendent 2000 analog filter. Wavefolded material sounds phenomenal on this, coming from Capt'n Big-O. Op Amp gain compensation means no loss of bass frequencies even at extreme resonance settings. Resonance will self-oscillate and produces a nice aggressive sinewave alone. With some coaxing you can track the self-osc w/ v/oct.
At the end you'll hear the filter output going into a phaser and delay.

Sound sources | Capt'n Big-O + GSE 101-VCO
Envelope | GSE 2xADSR
Phaser | GSE Polychrome Phaser
Delay | FX Aid
Recorded direct, no other mastering or effects.

Check my Reverb store for T2K-VCF availability and other cool modules http://reverb.com/shop/gstormelectro"

"Introducing the T2K-VCF: an 8HP analog circuit adaptation of the lowpass/ bandpass filter from an obscure 70s monosynth – the Powertran Transcendent 2000.

T2K-VCF is a 2-pole CA3080 OTA design w/ CA3140 op amp compensation at each stage. Translation = no loss of bass frequencies even at extreme resonance settings. Resonance will self-oscillate and produces a nice sine wave alone. T2K-VCF will fatten up routine oscillators - transform boring square/pulse and straight ramps into curvy vixens dressed to kill. Wavefolded material sounds phenomenal on this.

FREQUENCY | the initial Cutoff Frequency of the filter

RESONANCE | the depth of the peak frequency resonant feedback

IN1 & IN2 | Mix together 2 different audio signals, each w/ their own mix pot.

KB | Modulate the Cutoff Frequency w/ a V/oct signal or any other polar/bi-polar mod. Self-oscillation resonance will track v/oct loosely, but you will need to tweak the Initial Cutoff Frequency (Tune) and the KB amount knob (width tracking) to get there.

CV | Another Frequency mod can go here, range is greater than the KB input.

SHAPE | Select between LP lowpass or BP bandpass filter output w/ this mode switch.

OUT | the audio output jack of the filter


Includes a 10-pin to 16-pin Eurorack ribbon connector

Specs
8HP Module width
24 mm Module depth
14 mA on +12V
25 mA on -12V
0ma on 5V (not used)

The T2K-VCF pairs well with:

Wavefolders or VCO/wavefolders – Cre8Audio Capt’n Big-O, Dannysound Timbre

GSE 2xADSR – use envelope CV for some deep bass modulation

GSE Polychrome Phaser

Delay Effects – Happy Nerding FX Aid"
