Hand Of Glitch (Experimental drone music using iphone gyroscope)

Perplex On

"Revisiting an idea that’s coming back from time to time in one or the other form: iphone taped to the hand loaded with #gyrosynth + fx with #k7d and #dedalusdelay. Tilting the hand in different angles basically enables to wander through, inspect and pitch a custom sample. Served with #audioreactive particle projections."

New Bleep Lab's Bleep Base Teensy 4.0 DIY Platform & dadageek course "Making Synths with Arduino"

via Bleep Labs newsletter:

"I've got another session of my dadageek course 'Making Synths with Arduino' starting February 1st. It's a great course whether you're a beginner or if you already know how to code but want to get into Arduino and synths.

For this session I've got something new. Rather than just have a breadboard with a few knobs on it this course will use the Bleep Base, a new educational platform based around the powerful Teensy 4.0. This will allow us to experiment with more controls, i/o, memory, and speed without needing to troubleshoot breadboard connections and deal with add-ons that get in the way of learning to code your own synths and effects.

Sign up for the course soon and be the first to try it out. Less that 10 seats are currently open. Scholarships are also available.

The course starts February 1st and goes for 7 weeks, meeting in zoom every Monday at 6pm CST. Check out the dadageek page for all the info."

Virtual Music Introduces Polivoks Filter for the Waldorf Pulse

Waldorf Pulse + Polivoks Filter – Filter Comparison

via Virtual Music

"The Polivoks Multimode Filter integrated in the Pulse - a Synthesizer on Steroid!

The filter of the Russian Polivoks synthesizer is legendary for its powerful and mangy sound. Nothing in the world is that fat! The new Virtual Music Polivoks Filter Upgrade is an adequate replica. It is a small circuit board, designed for installation in the Waldorf Pulse.

Polivoks + Pulse = A powerful team!
The distinctive aesthetics of the Polivoks filter under the control of a powerful modulation matrix make sonic dreams come true. With relatively little effort, this Filter Upgrade transforms the Pulse into a fantastic sounding analog monster that even outshines some famous vintage synthesizers.

All features of the Polivoks Filter Upgrade
Vintage sound an analogue warmth for Waldorf Pulse / Pulse Plus
Authentic fat Polivoks sound Polivoks Filter Upgrade - Board
Multimode filter with low pass and band pass characteristics
Optional filter modulation by Oscillator 3
The orignal Pulse filter still remains
All filters can be selected quickly via the panel
Seamless integration into the Pulse sound generation
Kit for self-installation - optional installation by Virtual Music
Installation without any optical change of the Pulse
The filter's audio path is built in the style of the 80s
Handmade boutique ware built in small batch in Vienna
A very powerful Sound

The Polivoks Filter Upgrade sounds like the legendary original. The sound is creamy and powerfully mangy. Higher oscillator levels produce juicy saturation effects. With stronger resonances, the filter begins to scream passionately."

Waldorf's Kyra Gets an Update

via Waldorf

"Kyra Firmware ver 1.78 changes (compared to 1.74 )
- Fixed the incorrect play and MIDI transmission of Arpeggiator notes at very high note pitches.
- Fixed a problem where Arpeggiator notes could be left hanging on external MIDI devices. - Fixed incorrect display of some ModMat source names.
- Fixed a problem where LFOs in antiphase or quadrature phase started at a random phase.
- Added new Range parameter to LFO2 and LFO2 to allow rates up to 51.2Hz. Standard Range provides the existing rate range of 0.1Hz to 12.8Hz in 0.1Hz steps. Extended Range provides an extended rate ranging from 0.4Hz to 51.2Hz in 0.4Hz steps.
- Added the ability to adjust the phase of LFO1 and LFO2 in the range 0 to 180 degrees. The LFO must be in Polyphonic mode for this to have any effect. You can use the LFO Shape knob in Shift Mode to adjust the phase.
-Added the ability to adjust velocity scaling in the range 0 (no scaling, all notes played play at maximum level) to 127 (full velocity scaling). You can use the Amp EG Decay knob in Shift Mode to adjust the scaling.
-Added Latch Mode for the Arpeggiator. In Latch Mode, notes will play continuously until a new chord is played or the Arpeggiator is stopped. The existing mode using the sustain pedal can be selected by setting the Latch Mode to Sustain Pedal. There's a shortcut to start the Arpeggiator in Latch Mode by selecting Shift + Arp Enable.
-Reduced the default Dual Detune amount from 64 to 20 for Patches created using Init Patch.
- Removed the "Bass Delay" feature as it no longer served any purpose.
Kyra Firmware ver 1.74 changes (compared to 1.72 )
-Fixed a problem where the reverb damping on Part 2 could affect the reverb on Parts 3-8. -Fixed a problem that could cause very occasional clicks when the Phaser is used. -Corrected L and R being swapped over on audio outputs (analog and USB).
-Added a fast way to create an Init Patch by simply pressing Shift and Exit together."

Multivox MX-202 SN 834097

via this auction

"Multivox MX-202 String & Brass synthesizer Made in japan total copy of Roland RS-202
there's a cool article in Sound on Sound about the 2 : '' Opening up my RS202 produced a second surprise. The boards in the Roland may be laid out differently from those in the MX202, but apart from a bit of point-to-point cabling in the Multivox where the Roland uses connectors, you could pull a board out of one of these synths, and stick it in the other. I'm not talking just about geometry here. Other than the keyboard mechanism and the details of which screw goes where, these boards are the same, right down to component level.
In other words, the MX202 and the RS202 are the same instrument. ''
Everything works, got that great analog sound, and you turn on those chorus options and bam ahhhh here it is, that Classic Roland vintage sound."

Kind of interesting these were called the Nord Rack when they were primarily desktop synths. Note the placement of the jacks on the back would limit placement in a rack. I forget if you can adjust them like on the Virus synths.

Zoom ARQ-96 (synthesizer sampler sequencer)

via this auction

You can find some demos of the Zoom ARQ-96 in previous posts here.

"Here’s what I think the pros are: 1) Sounds amazing. The sound quality is great, competitive with Roland gear. I was quite surprised at how hi-fi this machine sounds. 2) The round shape is effective. Takes up very little space, and really works well for sequencing. 3) Depth. This is a full featured synth with plenty of tricks up its sleeve. You will be able to record complex, full songs with this. 4) Price. For what I am asking, it’s an unbeatable amount of power for the money.

Now for the cons. 1) You will need a MIDI keyboard. For sequencing, the ring thing is fine. Try to play it like an instrument, it’s awkward and tricky. If you jiggle it too much (and you will) it will think you are detaching the ring and there will be an interruption. This is not wear and tear to this unit, it’s inherent to this design. It really demands that you play it with the ring detached, which is awkward. And to be clear: this controller design is not great for playing. Break out the trusty Keystep. That’s the biggest flaw I have found. 2) Menu diving. All that power comes with a learning curve. The menu is deep. This thing does a lot. You will be downloading a big old PDF and spending some time. (Nobody gives you a full print manual anymore, it seems.) This kind of learning curve is a hurdle for all of these do-a-lot devices. I just want to be clear that this is not an exception. 3) Zoom orphaned the line. You can find some tutorials, there’s a manual available, but that’s it. Zoom bailed on it."
