Realistic Concertmate 660 (aka Casio CT360) keyboard demo - "Blue Edge"

Published on Oct 18, 2019 Alfonse

"Realistic Concertmate 660 (aka Casio CT360) keyboard (1988)

All sounds you hear in the track were made using the Concertmate 660 and run through various single effects pedals (TC Electronic Sub Up octaver for adding some depth to bass notes, the very synth-friendly Yamaha SDS CH-10MII chorus pedal, and the Boss DD7 digital delay). Parts were recorded to a DAW, where I added compression, EQ, and reverb as required. I sampled individual drum hits from slowed-down rhythms, to allow fresh beats to be built, rather than using the rhythms found on the 660 itself.

The aim of these videos is to see what you can create using sounds from ageing home keyboards together with current production tools. This one was a challenge, in all honesty, as the sounds are generally a bit thin and dull, but there was something about that Violin patch that felt right for a synthwave-inspired track...

Qu-Bit Electronix Prism

Published on Oct 18, 2019 CatSynth TV

"We check out the Prism multidimensional signal-processing module from Qu-Bit Electronix, with an assist from Big Merp.

5:10 Big Merp crashes the party

'Prism is a multidimensional signal processor that creates a framework for the spectral metamorphosis of any input signal. This stereo audio buffer can be navigated through on 3 axes, each of which provides a different sonic journey through its array of time based controls.

The X and Z planes are home to a flexible delay line capable of long clocked delays, slapback echo, or comb filtered vocoder-esque timbres. On the Y axis is the decimate control. This sets the audio fidelity of the buffer by manipulating the sample rate and bit depth of the output. A state variable filter with configurable low pass, high pass, and band pass outputs can be enabled at the beginning or end of the signal chain providing yet another dimension of spectral transformation. And thanks to its digital architecture, the current buffer contents can be locked in place with the Freeze control, creating glitch and beat repeat effects which can be synced to an external clock source.'

Rossum Electro-Music Linnaeus Thru-Zero State Variable Filter Ping Mode Demos

Rossum Electro-Music Linnaeus Thru-Zero State Variable Filter External Ping Mode Demo

"Following in the tradition of Evolution and Morpheus, LINNAEUS represents yet another Dave Rossum innovation in filter technology.

LINNAEUS is a stereo state variable filter that provides the unique ability to linearly modulate its resonant frequency through zero into negative frequency, while maintaining stability. With extensive voltage control of nearly every parameter, Linnaeus lets you manipulate the filter’s natural response curve in new ways, to create both subtle and dramatic timbral effects. And with a “one-knob-per-parameter” interface, LINNAEUS inspires sonic creativity that invites (and rewards) real-time interaction.

LINNAEUS’s cutoff/resonant frequency is exponentially voltage controllable from sub-audio to ultrasonic frequencies, while its resonant gain (Q) is exponentially voltage controllable from 0dB to greater than 60dB.

LINNAEUS’s channel output response characteristics are independently and continuously variable from Lowpass, through Bandpass, Highpass and Notch, to Low and High Shelving characteristics. Voltage control of the response characteristics are independently selectable for each of the two channels.

The linear thru-zero modulation is provided by an integrated modulation oscillator and/or an External Linear FM modulation input.

The voltage-controllable modulation oscillator can track the filter’s exponential frequency or operate independently. The modulation oscillator’s output waveform is continuously variable from Off through Sine, Triangle, and Sawtooth, to Square. The modulation oscillator output is summed with the external linear FM input and applied to the modulation index VCA, which controls the linear thru-zero modulation index from zero to 8X. The modulation index is, of course, also voltage controllable.

What’s with the egg?

Late in the beta testing process, our good friend and tester, Chris Meyer, raised the possibility of alternative behavior that would let LINNAEUS function as a self-contained (i.e., no input required) stereo oscillator and/or FM percussion voice with some really powerful timbral capabilities.

While we were initially hesitant to try to shoehorn the new functions into the existing interface, once Dave had prototyped them, it was clear to us all that they were just too cool not to include. So we’ve provided them in the form of alternate firmware accessed by pressing and holding the Egg button.

LINNAEUS is 16HP wide and 25mm deep.

Power requirements (max): 155mA +12V, 36mA -12V. Reverse polarity protected."

GOD's BOX Humpback // Multimode Eurorack filter with BAGS of character!

Published on Oct 18, 2019 DivKidVideo

"Here we have a newly re-panelled version of the Humpback filter from GOD's BOX. This is an 8HP SEM style multimode filter with a 2 pole response across the individual low, band and high pass + notch outputs. The input level can drive the filter for that lovely harmonic 'burn' and the two CV inputs affect the cut off with attenuators. It responds well to audio rate modulation for YOI bass, glottal overtones and odd pinged hits. The resonance is severely "hot rodded" beyond the normal SEM inspired filters giving a wide range of soft and warm bass to all out chaotic screams. I stumbled upon a weird way to create distance concrete car park reverb trails in your kick drums too. So skip around below and if you have any clue what's happening with that odd reverb I managed to create - let me know.

4ms SWN Custom Wavetables Demo

Published on Oct 18, 2019 UncertainMusicCorps

"A demo run through of some custom wavetables on the SWN. The wavetables have been designed specifically for drone use. Mostly the range of their spectral content is intentionally limited. Aiming for subtlety here (with one obvious exception). All of them were made using the module itself. No editing software involved. They were sourced by live sampling other synths and some orchestral recordings.

SWN is set up for a simple drone, with channels A & B dropped an octave and detuned against each other. The other channels also have some detuning applied. Internal LFOs are used to modulate the WT Depth and Latitude parameters throughout. Longitude and Sphere are modulated manually.

First run through is flat - all channels to 100% no LFO modulation of the VCAs. Then going back down the same wavetables with LFOs on and some chordal spread applied
Everything recorded dry, without EQ, direct to camera apart from the final 2 mins when some reverb is applied just for comparison."

Klavis Quadigy as an expressive ADSR

Published on Oct 18, 2019 Martin Doudoroff

"An exhaustive exploration of the ADSR features and behavior of Klavis Quadigy Quad Programmable Envelope Generator for Eurorack modular synthesizers.

• I didn’t realize until after the video was done that the PUNCH parameter is considered part of ATTACK for the purposes of the FULL ATTACK mode; so, with FULL ATTACK turned on, you’ll get at minimum the full attack and punch of the envelope; good to know
• I should have clarified that the time value of the HOLD parameter is relative to gate/trigger on, not relative to the end of DECAY
• I should have clarified that the HOLD parameter can be used in conjunction with gates as well as with triggers; with gates, the HOLD parameter effectively sets the minimum duration of the envelope (not including RELEASE)"

The goal is to allow the user setting up rich, interactive and dynamically evolving envelopes without the risk of breaking up a subtle and intricate patch once on stage. This is achieved by offering two main modes, one where full control is available and a Live mode where only the settings that are sensible using on stage are accessible.

Quad 7-stage envelopes
Continuous curve shape setting
Independent output level
Cycle capability with auto fit-to-clock
Elastic time stretching
5 internal clocks with tap tempo
External clock control
Multiply/divide and offset
Individual cycle ext. control
32 presets with naming
External preset control via CV/Trig
Simultaneous 156-point CV matrix
Morphing on presets and CV Matrix
Multi-editing for polyphonic uses
Live mode for easier/safer control
Graphical display
Real-time envelope stages LED indication
Current state retained over power cycle
Easy firmware update via an audio file
Skiff-friendly and compact module

Yamaha QX7 - When Sequencing Was New and Exciting

Published on Oct 18, 2019 Espen Kraft

"Yamaha QX7 digital sequencer from 1985 was the second MIDI sequencer released by Yamaha. The flagship QX1 was out of reach for most people so they released a 2-track "budget" sequencer for those not super rich.

You recorded everything on track 1 and bounced that down to track 2 as you went along. All separete MIDI channels were kept through the bouncing so you could build big multi-timbral arrangements if you wanted. Except for a dedicaded "copy" function and note editing, the QX7 had it all and it worked great for most things. The QX21 came a little later and it's basically the same sequencer for a lower price."
