Berlin School 960 Sequencer - Step Inputs/Outputs

video upload by O.Z. Hall

"This demo shows how to use the step inputs and outputs to control which steps in the sequence are played. This is a classic Tangerine Dream technique to break the monotony of playing the same 8 steps repeatedly.
I'm using the Swiss Daisy DSP as a virtual analog voice with delay. The controls I'm adjusting are the wet/dry mix, the envelop to VCF amount and the VCF cutooff frequency.
The simplest example of using the step in/out would be to take the step out from step 5 and connect it to the step in on step 1. This would result in the first four steps being played. (i.e. a reset to change the sequence length from 8 to 4 steps).
In order to quickly repatch to select the step out and step in, I have used a dual 4:1 selector switch, the Frequency Central 'Where" module:
https://synthcube.com/cart/frequencyc...
(no, I'm not paid for this link).
The top switch selects the beginning step; the bottom the ending step.
If the ending step number is BEFORE the beginning step number, the sequence skips the "ending" note and jumps (forward) to the "beginning" note.
One other wrinkle, the "step out" stays high for the entire step duration. I have turned this 100% "gate" into a trigger by running it through an A/D envelope.
One other note, I'm using row three to adjust volumes at each step."

Q169 plus Sequencer Jam #shorts

"The Synthesizers.com Q169 Oscillator ++ dual oscillator forms the main voice. Oscillator 2 is synced to Oscillator 1. The Voice of Saturn 10 step sequencer drives this jam. I'm manipulating the gates and the sequence length, as well as delay amount and time on the Swiss Daisy DSP module from Zebra Synth."

Q169 Oscillator++ and Q168 Oscillator++ Aid - Synthesizers.com

video upload by O.Z. Hall

"This is a demo of the new Q169 Oscillator++ with Q168 Aid, new from Synthesizers.com.
The only additonal gear was 1) Digital Delay 2) Sequencer 4) LFO++ 5) passive attenuator.
Digital Delay provided by the Swiss Daisy DSP by Zebra Synth.
Note that for VCO2 (synced sound) I'm using the new 'anti-sine' wave.
'The anti-sine wave is like subtracting a sine wave from a triangle wave and produces interesting harmonics.' with the fundamental removed, the other harmonics are much louder."

Let us know in the comments whether you think we should offer these for sale.
If so, would you prefer 5U/MU/Dotcom or Eurorack format ... or both?

ARP 2500 VCO 1004 as LFO with 921 VCO

video upload by O.Z. Hall

"This video explores the unique waveform switching and summing of the ARP 2500 VCO 1004. There are a few good videos of what the summed waveforms sound like. This video explores the 1004 VCO used as an LFO.

The patch is 1004 VCO (lfo mode) to Quantizer ( minor scale ). Quantizer CV out goes to System 55 VCO 921 ( CV in ). The 921 audio out goes to a 1047 Multi-Mode VCF for some sound shaping. The 2500 Dual Envelope 1033 is provides a percussive envelope for the VCF.

The Swiss Daisy DSP ( ZebraSynth.net ) provides delay and reverb to finish off the sound."

"First, let me thank Martin Peters for teaching me the dotted eight note delay trick for Berlin School delay. See link below. Martin is one of the worldwide masters of Berlin School today.

The Z506 Swiss Daisy DSP is a module based on the https://www.electro-smith.com/ Daisy board, with a microprocessor and high fidelity audio I/O. The Z506 is available in MU/Dotcom format from https://www.noisebug.net/. It is available in both Eurorack and MU formats."

About this sequencer.
I purchased this sequencer new in 1977. I sold it to Ken W., a friend, perhaps 10 years later. He has kept it in great condition, but some of the ICs failed. The clock did not work. The sequencing did not work. I repaired it over the period of two weeks."

ARP 2600 plus SwissDaisyDSP Pluck Mode with distortion

video by O.Z. Hall

"The ARP 2600 is providing CV/gate to control the Z506 Swiss Daisy DSP in the new 'Pluck' mode. The Frequency Central MethAmp module provides distortion.

The Swiss Daisy DSP pluck mode uses a Karplus-Strong algorithm to model a plucked string ( think "Rings" ). This plucked string provides a great foundation for driving the MethAmp distortion module.

The Frequency Central MethAmp is a clone of the famous 'Big Muff' distortion pedal used by Hendrix and many others. I could have used the preamp section of the ARP 2600, but the MethAmp also provides tone control, as well as a 'regeneration' control that did not appear on the original Big Muff. The regen can easily cause feedback (frequency controlled by the tone control).

BTW, I love this video on Karplus-Strong synthesis:" [posted here]

Z506 Swiss Daisy DSP - looping AD demo

O.Z. Hall

"One of the modes of the Z506 Swiss Daisy DSP is 'oscillator' mode. The oscillator section (left half) can be used as a 'filterless' voice when combined with the ADSR and VCA (right half). Once of the waveforms is 'Noise'. In VCO mode with the Noise waveform, the bottom left knob is a 6DB per octave lowpass filter (tone control). The noise spectrum can be varied from white noise to pink noise to a little darker than pink noise (but not random), since the audio output is AC coupled.

There is a looping behavior in the ADSR when the sustain is below about the 8:30 knob position. This video explores/exploits that behavior."

Z506 Swiss Daisy DSP - Reverb/ADSR/VCA mode

O.Z. Hall

"This is a demo of the Z506 Swiss Daisy DSP module from Zebra Synth (ZebraSynth.net). The module features an ADSR envelope generator, a VCA on the right half of the module. These functions remain the same with all of the different "Modes". The functionality of the left half of the module changes from mode to mode. The modes are VCO, VCF, Digital Delay, Reverb, Dual Resonator.

This is video covers the Reverb mode. The signal path as a high pass filter on the input and a low pass filter (for damping) on the feedback loop from the reverb output back to the reverb input. There is a modulation input to modulate the reverb size from an external control voltage."

This is video covers the Dual Resonator mode. There are two resonators. Each has a center frequency control. They share a common Resonance control. The Wet/Dry control mixes the dry and filtered signal to the output. There is a modulation input to modulate the center frequency of the resonators from an external control voltage. A positive control voltage will increase the Res 1 frequency and decrease the Res 2 frequency."
