RF dawless jam 147bpm

video upload by Radical Frequencies Modular

"Patch: Bass is the Dpvco mixing the alpha square with beta saw slightly detuned into the RF transistor mixer and into SH Vcf. The decay of the envelope filter is voltage controlled by Lucky Voltages giving a bit more groove.
The lead is a simple saw into the Diode Dream Vcf which can make internal fm from Vcf input to the filter cv frequency. This resonance sounds so bubbly and glassy with beautiful mid high frequencies!
All drums are from different sources mostly analog mixing into a vintage 70s mixer. The jam is directly recorded into daw. Sequencing is done with Beatsteppro."

"Patch: The bass is the alpha pulse waveform from Dpvco into Diode Dream Vcf. Listen at the last 20 seconds of the video where I open the Alpha pwm pot (the beta vco triangle is internally connected as the PW modulator of alpha vco) and the opening of the filter cutoff for producing this fat warm analog pwm bass !
The goa style melody lead comes from admvco saw through the Scota Vcf !
All drums are from different sources mostly analog and I mix them through the RF audio cv mixer using the transistor output."

"Patch:
The bass is the alpha saw from dpvco and the sub oscillator form waveshaper module into rf transistor mixer and then into diode dream Vcf 5 pole low pass .
The fm bleeping melody lead comes from dpvco beta saw through the amazing Scota Vcf which a wonderful module for instant fm leads and sfx ! Of course a lot of modulations are taking place here and there ! Sequencer is the beatstep pro and the drums are from rd6 and volca sample ."

RF Modular Psytrance fm lead recording jam

video upload by Radical Frequencies Modular

"My best wishes for all synth modular tweakers out there ! Here is a Radical Frequencies modular Psytrance fm lead recording jam.

Patch: DPVCO in exponential fm mode and synced sends both saws into RF Mixer and after into SCOTA Vcf bandpass input. The alpha section of Scota Vcf is used as bandpass filter and beta filter as lfo modulator to alpha filter reaching audio range fm capabilities ! The filter is also modulated by lucky Voltages which is in sync with our daw. The final RF Vca is voltage controlled by RF VC ADSR Generator which is modulated in decay and release stages. All other sounds ( drums and bass ) are in the box."

Radical Frequencies Introduces Diode Dream VCF

"Audio path : Dpvco into mixer and then into Diode Dream Vcf .
The oscillator wave at first it’s saw and later in video becomes square. The sequence is in 303 acid style using a lot of RF modules like VCAs - mixers and vc envelopes for making the 303 accent function. A modified RD6 is used as drum machine."

"5 Pole diode ladder filter with multistage variable out of low pass and band pass

Diode Dream VCF is a 5 Pole diode ladder filter but instead of diodes, the circuit in the filter core section, uses transistors in diode configuration.

The filter has a switch selecting between 5 or 4 STAGES of filtering.

You can access the low pass output via the LP out jack.

There is also a VARIABLE out with a dedicated knob. That knob is a mixer of the different pole outputs that are opposite in phase and in the middle, it gives a band pass [BP] out. When in BP the gain is lower in volume which is completely normal.

VARIABLE mixing knob can be altered from less poles to more poles, more specific, VARIABLE out sends 1 or 2 stages at left side and 4 or 5 stages in the right side. That depends from the position switch of STAGES, so if the switch is in 4 position the VARIABLE out sends 1 (full CCW) and 4 (full CW) stages. If the switch is in 5 position, the VARIABLE out sends 2 (full CCW) and 5 (full CW) stages.

This arrangement also affects the Band Pass slope.

The CV-FM input has a dedicated pot for cv amount that is normaled to the audio input of the filter.

This allows for instant fm tones as the audio input becomes a modulator for the filter frequency.

If there is a jack inserted this connection is broken and you can use this knob as cv amount of an envelope or lfo.

There is one audio INPUT with amount pot and a 2nd CV input jack [CV2].

This CV input can be used as volt per octave input control. When the filter is in full resonance the module can be used as sine wave oscillator with good tuning of 2 octaves.

There is a resonance BOOST switch in order to achieve self oscillation. If the RES knob is fully closed and the BOOST is on, then the filter has still some feedback that would be very useful to emphasise the highs and lessen the low frequencies. When BOOST is off and the RES knob is fully closed and the INPUT level fully open the sound will be a bit oversaturated, so you can try turning down the INPUT level knob at 2-3 o’clock .

The filter has discrete through hole components with low noise transistors that are hand selected one by one with very high hfe values and are also matched in pairs for the buffer differential amplifiers and the input output stages of the ladder. An IC opamp is used for resonance gain compensation.

In the original design when the resonance is turned up the gain of the filter decreases drastically. The filter now has resonance gain compensation and while it still loses some gain when in resonance, the gain difference, is now is acceptable and the sound of the filter is pure and warm without losing the character. The resonance compensation is achieved by increasing the input gain while the resonance opens, so this gives a special character.

Because of the filter design the input signal does not clip instantly but instead it saturates the sound musically and the more you push it the richer the output in harmonics and natural and musical compression.

When the resonance is in self oscillation and the audio input is pushed, the sound gets glassy and squelchy. This filter gets acidic but it maintains the clarity of the high end, yet sounds warm and very rubbery. Detailed bass, creamy mids and crispy smooth highs.

Many different tones are waiting to be discovered by the user dealing in different combinations of the input gain, the resonance, the frequency FREQ knob and the VARIABLE shape of the filter."
