Future Retro Vectra Synthesizer: Tremolo Piano - in and out of sync

video upload by artoftravelogue

"This is a patch I created on the Vectra Synthesizer. In this patch, each of the four voices have its own LFO for amplitude control. They synchronize to the press of a key. If you don't press all notes at the same time when the XY joystick is in the down position, then they will synchronize, but be out of phase with each other. I use the XY joystick to change the speed of each LFO, which in turn creates a sound of free running LFOs that are not in sync with each other."

Future Retro Vectra Synthesizer Demos

video uploads by artoftravelogue


1. Future Retro Vectra Synthesizer: choir sound
Here is a demonstration of a male choir patch that I made on the Future Retro Vectra synthesizer. Even though this synth engine is normally layering the 4 voices (oscillator pairs with separate envelopes) as a single voice, it also has a nice paraphonic mode where you can play 4 voices simultaneously through the single filter. I assigned the xy joystick to the vibrato rate.
2. Future Retro Vectra Paraphonic trick
One thing about paraphonic synthesizer voices, is that the notes are retriggered through the filter and final VCA. This can be very useful in a patch or sound like this, where some of the voices are still playing the last chord until cycling through all 4 voices. The XY joystick in this patch changes a minor chord to a major chord by raising the third a half step. If the joystick is in the middle between the major and minor third, then you only play the blues with this patch, just kidding.
3. Future Retro Vectra Synthesizer: beat and sequencer example
The Vectra has a unique feature where the envelopes can be delayed for each of the 4 voices. By creating drum sounds then using this delay to create rhythms and sequencing a simple pattern using this drum loop, you can get some interesting rhythms. The mix joystick lets you control the balance between the drum sounds. the XY joystick is changing the delay on 2 of the voices.
4. Future Retro Vectra Synthesizer: Cello sound example
The Future Retro Vectra Synthesizer has a powerful voice architecture. Not only does it allow a similar wave blending engine like the famous Prophet VS or the ModWave, but it also has 4 joysticks to mix, filter, and adjust the sound as you are playing it. The XY joystick is assigned to vibrato rates and the aftertouch is assigned to the vibrato amount.

"This is a video to demonstrate the EML POLY-BOX. The POLY-BOX was created in the late 70's to allow polyphony and chords to the modular world. It takes an oscillator input and uses phase-lock loops and top octave divide down circuitry to give you all the notes of the western equal-tempered chromatic scale.

Using this as a processor for a Roland SH-101 is shown in this video. However, any synthesizer can be used, and one can even confuse it more when 2 or more oscillators are mixed into the input of the POLY-BOX."

Voltage Controlled Motor Driven Oscillator Tonewheel

Published on Mar 23, 2019 artoftravelogue

"This is a demo of my prototype for a voltage controlled motor driven oscillator. This was developed in 2015 and performed with later that year at Chicagoland's Knobcon. The sound and everything you hear is directly from the instrument and not processed in any way. Check out my channel or website for other interesting instruments."

Wave Replacement Synthesis

Published on Feb 14, 2019 artoftravelogue

"This video describes a powerful form of analog synthesis that can be used as a building block for complex and interesting sounds. Forget the confines of subtractive, FM, additive, east coast, west coast, and all the other terms that have been keeping us in the 1970's. Explore a Wave Replacement patch and you will find a whole new palette of sonic possibilities. This presentation is similar to the one that I gave at Knobcon. I also have several blog posts about this."

The Magnetic Table: A CV controller for Modular Synthesizers

Published on Jan 7, 2013 artoftravelogue·2 videos

"Here is a demonstration of a CV controller that I built. It is a simple pendulum with a magnet at the end. The magnets on the table can be moved and can either repel or attract the pendulum. More information can be found at or more specifically here:"

Synchonizing Electronic Musical Equipment and Acoustic Drums

YouTube Uploaded by artoftravelogue on Mar 12, 2012

"The ability to have sequences of different devices play in time together can be a challenge. In this video, I demonstrate how I synchronize various equipment. MIDI and DCB standards can also be easily synched, but are not shown in this video. I use primarily DIN Sync and analog clocks (including the Garfield MiniDoc) for this demonstration. The Casio and the DR110 have been modified to accept a clock input. The solenoid drum triggers were built by me and allow for dynamics (accents) - the roll in the drum pattern is programmed using a pulse LFO with an S/H modulation for random variation. There is more information on modifying clock signals at"

Sequential Circuits Programmer comes in at 1:48. Aries modular audio comes in just before that. Watch through to the end for the drums being triggered by the Modcan.
