Modular Jam 2022 Nov 12


video upload by O.Z. Hall

"I'm using the Korg ARP 2600 for the main sequence and clock. I have a secondary sequence on the 5U format Modular.

The lead voice is also on the modular. A few specific modules that I'm using:
Electro-Smith CEM3340 VCO
Electro-Smith SSM-2044 OTA filter (Prophet 5, Rev 3).
a Serge Resonant Equalizer
a wave folder
The looping envelope on the Z506 Swiss Daisy DSP, modulating"

ARP 2600 Ring Modulator Demo


video upload by O.Z. Hall

"This demo just scratches the surface of what you can do with a "Ring Modulator" (aka Balanced Modulator, aka 4 Quadrant multiplier).

Here is some technical detail ...
The term quadrant used below refers to cartesian coordinates ( e.g. x/y graph with 4 quadrants ).

Regarding two quadrant multipliers (e.g. VCA) versus four quadrant multipliers (e.g. Ring Modulator).
Here's a short definition;
A two quadrant multiplier will multiply two signals together
one (bipolar) input (the carrier) (e.g. VCA signal input - audio or a DC voltage - e.g. +/-5v )
another (unipolar ) input (the modulator) (e.g. a level control input, e.g. an envelope 0-5v ) .
A 4 quadrant multiplier will multiply two signals, both of which are bipolar.

The both multipliers create "sidebands", whose frequencies are the sum and difference of the two inputs. E.G. 100 Hz (carrier) and 25 Hz (modulator). The sideband frequencies are the sum (100+25 = 125 Hz) and the difference (100 - 25 = 75 Hz) .

A 2 quadrant multiplier is an unbalanced modulator while 4 quadrant multiplier is "balanced". This means that.
The VCA (unbalanced) would output the carrier and the sideband frequencies (100 Hz, 125 Hz, 75 Hz).
A ring modulator (balanced) outputs only the sideband frequencies (the carrier is suppressed)."

ARP 2600 filter magic! #shorts


video upload by O.Z. Hall

"#shorts ARP 2600 is played by a simple sequence (from the 3620 keyboard sequencer). The voice is VCO1 to VCF to VCA with Reverb. The VCF is modulated by VCO2 in low frequency mode. The magic happens when the output of the VCF is routed to the Filter Cutoff Frequency CV input.
The Digital Delay is provided by the Swiss Daisy DSP.
Note that the initial VCF cutoff frequency is a sensitive parameter. Also very sensitive is the VCO1 level in the VCF audio input mixer.
The behavior is different from the Type 1 filter to the Type 2 filter. Both work, but they behave a little differently."

ARP 2600 w GRP R24 Sequencer + Swiss Daisy DSP


video upload by O.Z. Hall

"The GRP Synthesizer company's R24 sequencer is driving two voices on the ARP 2600 and a third voice provided by the ZebraSynth.net Swiss Daisy DSP module, in "pluck voice" mode, with delay and reverb.
I'm using several features of the R24 including:
3 separate sequences (CV/Gate out ; MIDI also available)
Some sequences use the "ratchet" feature to double gate a single step.
The second row is only 6 steps, to provide a poly-rhythm for greater complexity (less monotonous ).

Thanks to my long time friend Rod Scott for loaning me the GRP R24. Check out his channel:

ARP 2600 with ARP 2500 ModAmp 1005 in Depth


video upload by O.Z. Hall

"This is a detailed tutorial on Behringer's ARP 2500 ModAmp 1005 module. We used the the ARP 2600 oscillators as inputs so that it would be easy so see the connections. The ARP 3620 duophonic keyboard played a 'key' role in this demo (pun intended)."

ARP 2600 Berlin School Delay and Reverb


video by O.Z. Hall

"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."

ARP 2600 - Quantized Sample & Hold


video by O.Z. Hall

"This is a short sample and hold demo using a quantizer. It is NOT random sample and hold. VCO1 is in low frequency mode. The sawtooth output is the input to the sample and hold. The result is a series of semitone patterns that are varied and interesting."

ARP 2600 + Dual LFO Sequence Demo


video by O.Z. Hall

"My friend James Carr built a cabinet for Eurorack modules to fit beneath my Korg ARP 2600 FS. It has two rows of 126 HP. The size is the same as three rows of 84 HP, like the Doepfer 9U cabinet.
I'm demoing a technique for generating a sequence by mixing the output of two LFOs. The output is quantized for easy tuning. The trigger input to the quantizer controls when the quantizer output voltage is updated.
I hope you enjoy this demo."

ARP 1601 Sequencer with ARP 2600 synth


video by O.Z. Hall

"This is a demo of a 1977 ARP 1601 Sequencer. It drives the ARP 2600 synth.
Digital Delay is provided via the Z506 Swiss Daisy DSP.
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 Shepard Tone


video by O.Z. Hall

"This is an approximation of an 'ever rising' Shepard Tone. The Sheppard Tone is an audio illusion creating the impression of a tone the rises forever. A similar video illusion is the barber pole, where the stripes appear to continually rise upward.
This patch is not a legit Sheppard Tone, but it is similar.
I hope you enjoy it."

ARP 2600 Sequence Jam


video by O.Z. Hall

"ARP 2600 provides the lead.
Z506 Swiss Daisy DSP provides the 'pluck'.
Intellijel Metropolis sequencer drives the Swiss Daisy DSP.
Frequency Central MethAmp provides overdrive as well as a voltage controlled tone with "regen"eration (resonance/Q).
ES FV-1 modules provide digital delay and reverb.
This module is based on the Electro-Smith.com FV-1 submodule. RecklessExperimentationAudio.com provided the prototype PCBs and panels. Thanks Mikhail!

I hope you enjoy this jam."

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]

ARP 2600 - duophonic 3620 keyboard


video by O.Z. Hall

"This video explores the possibilities provided with the ARP 3620 keyboard duophonic feature. Interval latching controlled via footswitch is one feature. Another is routing only the CV2 (Upper Voice) control voltage through the Lag Processor, so that only the upper voice has portamento."

ARP 2600 presets with Sequential Circuits Model 700 Programmer


O.Z. Hall

Left channel audio only on this one.

"The third product from Sequential Circuits was the Model 700 programmer. It allowed monophonic synthesizers like the ARP 2600, Minimoog and ARP Odyssey to have the following parameters preset:
VCA envelope and amount
VCF cutoff, envelope and amount
VCO tuning (for 3 VCOs).
The Model 700 programmer was the precursor to the revolutionary Prophet 5 synthesizers. The Prophet 5 used the same knobs, switches and color scheme.
This video demonstrates this 1970s Model 700 programmer with a reissued ARP 2600."

ARP 2600 vs NLC 1088 Mogue Mixer/VCA


O.Z. Hall

"The is a review of the NonLinear Circuits 1088 Mogue Mixer/VCA. We compare the 1088 to the 2600s VCF mixer and VCA. The 2600 is clean an precise (at unity gain). The 1088 can be clean, but can also distort in a very musical way. Take a listen!
