"Monophonic synthesizer Altair 231 (Estradin factory, Zhitomir city) is intended to play different sounds from the imitation of natural instruments to complicated synthesized electronic timbres, sound effects, percussion sounds & so on. There are a four-octave keyboard & a wheel to pitch control. There are also controls for parameters on the front panel, an output for phones, an input for a pedal. The instrument consists of four main blocks of sound synthesis - Generator, Mixer, Filter and Contour.

Synthesis is based on 3 master oscillators (each of them with different parameters of registers) waveform, frequency modulation. There is also a generator of white & pink noise. Low-pass filter with main parameters gives the possibility for keyboard tracking. Portamento adjustment knob is provided. To tune a pitch the tone signal is used (440Hz) It provides a linear input to connct an external sound source to Altair. Output and input sockets are 1/4" jacks

Altair 231 is an almost identical copy of the famous Moog Minimoog, made in the former Soviet Union. Biggest difference in sound is caused by different brand of components: Russian equivalents are used everywhere.

The oscillator board is based on the older version. However, the Russians were clever and used multi-turn potentiometers for the scaling controls. Result: Synth stays in tune better. The Russians didn't seem to have reverse log pots. Because of that, the resonance control was wired backwards and a regular logarithmic pot was used instead. Other than that, the synth seems to be very robust and easy to service - the real Mini schematics come for good help when comparing the component numbers etc. It sounds like a Mini! I heard a Mini with the newer oscillator board and I think that's the reason for minor differences in sound between it and the Altair.

BugBrand Modular & MuSonics Minimoog - December 2, 2014

"If I remember well the bass drum comes from the BugBrand Quadrature Sine that I used a lot for BD services.
Back then I was testing the BugBrand with different synths."

Klavis-Twin Waves MKII Dual VCO/LFO demo (no talking )

Dziam Bass

"Hi All.
Today I have a small demo with quite an extensive Twin Waves MKII module from Klavis
It is a really interesting Dual Oscillator with many functions, available algorithms, built-in quantizer, dual LFO, Through zero and linear FM ,and many other functions.
Basically at the beginning of the small demo waves, as you can see very quickly you can also get Super SAW.
then you have a few examples in sequence or modulation and for each I also used CalTrans for the perfect trace and for low transposition and the Mixwitch module in this case as a mixer with Quadigy -Quad Programmable Envelope Generator for modulation.
each patch of the 7 available is slightly different to show the versatility of the Twin Waves module.
For me this is Beast in small HP module.🔥🔥🔥
for example, some functions available from the module description."

TWIN WAVES MKII

Voltage-controlled Dual VCO/LFO/random
Two oscillators independently set as VCO, LFO, or random generator
Features in VCO mode:
V/Oct tracking over 10 octaves
Through zero and linear FM
Sub-octave output
Hard & soft synchronization
VCA control and CV algorithms selection
Quantizer with various scales
20 algorithm-based synthesis types among:
Wave shaping
Phase modulation
Phase positioning of multiple waves
Up to 5 stacked oscillators in tunable unison
Self-sync with phantom oscillator
Additive synthesis (7 waves)
Variable bit reduction (bit-crushing)
Ring modulator with its own 2nd oscillator
Noise with LPF, BPF, or resonant filter
Features in LFO mode:
Simultaneous signal and trigger outputs
External wave synchronization
Clock controlled rate with voltage controlled multiplier and divider
CV and knob control of output level
Algorithm based wave engine with a selection of:
Wave shaping
Phase modulation
Random levels and vectors (also Brownian)
Randomly spaced triggers and waves
Display with contextual icons and instant reminder help text
LEDs indicating potentiometer vs. value matching, switch settings and output signals
Automatically saved settings for instant recall at power on
Firmware update by playing an audio file via the front panel
Compact and skiff-friendly module

This MKII evolution brings a redesigned layout, additional knobs for more hands-on fun and semi-modular cross-patching between sections.
All of the original features are present: a top selection of synthesis techniques, each with their key parameter directly at hand, enriched by a full set of complementary features.
More than ever the Twin Waves is versatility at its best.

Modal Skulpt: "Four by Fourteen" (+ Running Score)

Kris Lennox

"A while back I posted a piece on the OB-6, titled 'Six by Eighteen' i.e 6 voices, 18 beats in the bar. In this work, I'm embracing the 4-voice nature of the Skulpt, and writing in 14/16 time. Running score included to illustrate the 4 voices i.e if you can read music, you should be able to follow each line independently with the aid of the score.

Musically quite complex, in terms of rhythms. The central voices are playing a 4:3 Superparticular (i.e Geminus Sesquitertius).

In terms of the Skulpt: you're hearing 5 recordings. I made an initial recording with the Skulpt performing all 4 voices simultaneously (PS the Skulpt managed fine RE performing all 4 parts simultaneously), but from a compositional standpoint, it makes more sense to have a unique timbre for each voice. I re-recorded each voice (unison, as opposed to poly mode) with a unique timbre/patch I created.

The primary sound is still there - but part of the mix. However, everything you are hearing is the Skulpt (with the exception of standard production work i.e reverb, panning etc).

Enjoy/all best
Kris"

Akai AX60 | The best and worst synthesizer Akai ever did

Espen Kraft

"The Akai AX60 from 1985. A one-vco-oscillator per voice, with the ability to patch in voices from their line of first samplers as a 'VCO 2'. Very unique."
