MODULE: TPC SLIM VCO
ANALOG OSCILLATOR, SOUND SOURCE, LFO WIDTH: 12HP CURRENT: TBA DEPTH: 1.5" Clearance, 1.3" min. ---------------------------------------------------------------- Two Stacker PCB manufacturing method. 1. Control PCB 2. CORE vco PCB ---------------------------------------------------------------- Discrete Triangle Core VCO What does this do? This is an analog vco based on the Bergfotron Advanced VCO. It has heavy modification compared to other buchla vco's. It will track much better then the competition. Why? because this is using a VCA based tracking system instead of the matched transistor system. The 'Lock' switch allows for setting up your favorite reference Frequency. For example you can set it up on Zero Volts equals low Note 'C'. You use this as a sound source. You use this as a precision LFO. You get a bonus analog sample and hold. There are two possible sound source outputs: -Wave Out. This has 8 possible wave shapes: Triangle, Saw, Double Saw, Pulse Width, Sine, Ramp, Even Harmonics, and Double Pusle wave. All of this is selected by push button. The selector circuit is using a Precision DG412 IC chip, so there is absolutely no bleeding. There is of coarse CV input for the selector (by Triggering). All 8 waves are roughly -5/+5 (more than). I like my signals hot, so it is a bit more then your wimpy vco's. My clients know the way I roll already. -(Positive) Static Square Wave Out. This is a great clock source, it is also a great sync source for other products. The analog sample and hold is using the internal VCO as the 'clock'. You simply patch a sound source on the 'input' and use the output to monitor the result. The (red knob) Tune knob above is used to control the S&H rate. This product is the evolution of the 'Transistor Pyramid Core' saga. This product has all the research and development I spent working with Analog vco's. Price: $289.00 |

MODEL: BLM JPJFET VCO
Analog Saw Core VCO Width: 6hp Depth: 1 Stack PCB. Skiff Compatible. Current: -32mA, +35mA Circuit type: Analog What does this do? This is an analog Voltage Control Oscillator that is Saw core based. It uses a JFET part inside to generate the Saw wave. This is very similar to a famous Roland Vintage product, but this is using modern equivalent parts. The 1V per Octave circuit is also not transistor based. It is using a modern VCA circuit for 1v/octave tracking. The 1V/octave circuit is also using the recent Op Amp OPA1678. OPA1678 has 110db Noise Floor, and 0.0001% THD. The power rail capacitors are Tantulum type, and the timing Capacitor is a 2% 4.7nF through hole film type. 0.1% Reference voltages were used for the tune and fine tune. Wave Outputs: Saw wave, Pulse Wave. Both are operating from 0v. -5v/+5v (AC signal) Pulse Wave has a Pulse Width Modulation input. Saw Wave is static, and the PWM does not do anything to it. Modulation Inputs: Linear, and Exponential. 1. Modulation with Attenuator. Exponential Type. 2. Linear with Attenuator. 3. 1V/Octave Direct Input. Hard Sync Input. This requires a Positive Square Wave. Softer AC wave forms will do a very soft sync effect. Buy One Now |

Module: Phobos Lunar LFO V2.0
Width: 12hp Current: +80mA,-50mA Analog PLL based LFO/VCO This module contains about 5 modules in one. You get a lot of features. This is using a Phase Lock Loop based internal patch to create the oscillation (LFO). I then give you access to the clock divider used in the Phase Lock process. Think of this module as a 'phase lock loop for dummies'. Just play and forget kind of module. No menu diving or complicated stuff to remember. This LFO can go audio rate or really slow using the toggle switch to decide LFO/VCO mode. There is an internal CV switch for you to select from 6 wave forms. The special wave form is the step generated wave. It sounds like a quantized ramp wave, and moves at half the overall internal lfo rate. There is a nice Level out knob to control the LFO wave output. This LFO has very HARD sync, that will reset the lfo. The other half of this module contains a clock divider that also uses a CV selectable output. The clock divider can also go audio rate and sound like a sub harmonic generator when in audio rate. At very high frequencies (COARSE knob fully clockwise), the clock divider will lock up, this is due to the cmos chip, this is normal. The clock divider can be used with internal clock or external clock. This is a fun performance type of lfo with just about all the features an LFO should have. There is 1v/ octave tracking of about 4 octaves when used as an oscillator. This product is for most part more of an LFO. The best patch one can do with this product is a 'cross' patch from the Phobos Lunar LFO, and have it patched to your Oscillator module. Then patch your oscillator to the CV waveform select on the Phobos. Hear what your oscillator sounds like, it will blow your sound pallet. I demonstrated this patch at the Knob Con 2016 conference.

Model: BLM CMOS Fx Processor MK2
Width: 16hp Current: +35mA,-34mA PCB Stack: 1 level. Skiff compatible. What does this do? This module has all the internal circuits to complete a voice: sound generation + envelope generation + amplifier control. The sound generation is interesting. The core is using 3 CMOS based oscillators that are performing exclusive 'or' logic. This is known as 'XOR' ring modulation. This entire circuit is being voltage starved, a technique common among the advanced circuit bending hobby. For example, portable vintage toys that use batteries sound different as there batteries loose voltage. I designed a CV controllable circuit that simulates the 'dying batteries' scenario. This is where the product's name comes from: CMOS FX Processor. Incoming audio is internally conditioned to be those dying batteries. To my knowledge I don't think there is any other euro format product that uses this technique. -CMOS FX INPUT jack has a capacitor on it's signal path, making this an AC input. -MOD INPUT jack is a DC signal path. -FM INPUT jack is also a DC signal path, but with level control (attenuator). Envelope Generator This is a digital based 1 shot circuit, that has 8 wave forms. The decay knob controls the tail of the envelope. There is no parameter for attack. Some of the wave forms have set attack times if you require some 'fading' in on the control. -Regeneration 'REGEN' parameter is a feedback. This controls the looping of your envelope. -Delay parameter controls the time until the next 1 shot of your loop. -Decay knob needs to be adjusted as you experiment using Regen and Delay parameters. Shorter decay times work best and make the looping faster. -Envelope Output is 0-10V. Amplifier Control The internal circuit is an OTA based '13700' vca design. -Accent input jack is a POSITIVE only conditioner. For example if you patch a -5/+5v signal, only the +5v portion reaches the VCA control. This is good for making the audio louder at given intervals, but not making the audio 'mute'. -VCA CV input jack is a direct DC coupled input. This will make the audio fade in and out of volume. Both positive and negative values make it to the VCA control. How to use this module. For best results you will need a sequencer or sample and hold from a digital fancy module. You can practice first by patching this to the 'FM' input and find your sweet spot with its level. You will need to patch a 'tempo' to the trigger or you can use the W Pulse clock to trigger this product. Once you got the hang of the module, make a sequenced based patch with your other modules. Use the CMOS FX Processor at the end of the audio signal path chain to 'Process' your audio. Your going to here some bizzare techno. If you have a scope, the waveforms on the output are really crazy to see. Price $168.00 |
