Expert Controller for Yamaha VL1

video upload by Robert Skerjanc

"Demonstration of the hardware prototype. It can edit the complete physical model of the VL1. Musically not much enlightening, but showing some first impressions. See also my home page:"

"This is my vision of an ideal hardware controller for the famous Yamaha VL1 synthesizer. After my experience of making a HW controller for the FS1R, I decided to create an new user interface that deals easily with hundreds of parameters to control this beast. The case is designed as a 19″ rack mount, the same size as the VL1m module. As the name implies, it can edit all physical modelling parameters as you were able with the Yamahas Expert Editor for Macs.

Individual dials for all parameters rendered quite impossible, so I found a way to divide the parameters into several pages of 16 parameters and show the content on an OLED displays.

You have 7 groups on the front panel: Global, Control, Effect, Driver, Physics, Pipe and Modifier. Each group has several buttons and LEDs to indicate the current selected parameter page. In the next image you see that the page for editing breath noise and excitation is selected, and the 16 dials are assigned to the belonging parameters.

The dials are endless encoders with haptic clicks. The displays are divided in two halves, upper display half describes the parameter name and value for the upper dial and vice versa.

That’s it: you have a good overview about the whole context and you can easily dive into all parameters."

Nice Filter & Modulation on FS1R
Bottom Right is FM-Modulation Wheel
Bottom left is ADR
Top right is Filter Section

Resonance on Quantum and this Taurus Sound is tricky.. little percentage up and it is .. fieps.. ☣️"

Kickdrum Modulation on Yamaha FS1R / FM Synthese/ Minimal Beat Generator /

video upload by DACHI Klangmusik

"Kind of Beatflow starting 28:00

Modulation Faders on OP 1-8
Preset I 064 Drumkit
Arpeggio on 120 bpm with 2 Notes
Osc Form of OP 8 is set on Formant (FS-Synthese)

FS1R FM Synthesis w/ Operators - Kickdrum Modulation on Skerjanc Controller- trying to find the „Kick“ - no effects added

Algorithm 25:

Modulations on:
Attack Decay Release
Filter (Scaling/ Scale BP/ F)
EG Depth

.. and no.. I am not a DJ .. 😂

this kind of fading and tweaking has technically almost nothing to do with a DJ

Just 2 sound sources X
each 2 signals per second X
are generating all the wave-signals you hear"

FS1R improv with the wonderful Skerjanc controller

video upload by Video muzak

"More or less random noodling with the Yamaha FS1R using the hw controller designed and handbuilt by Robert Skerjanc. The Blokas Midihub (small grey box) helping things out. Just playing with the formants, FM and the nonvoiced operators at the part level. Audio could be better."

Yamaha FS1R Unleashed

Robert Skerjanc

"A small session controlling the FS1r Synthesizer live with a custom hardware controller."

Custom controller for the Yamaha FS1r. Almost looks like custome eurorack modules.

Curious how many of the FS1r parameters it controls. I once made an 80 page editor with Touch OSC with over 1000 parameters. It was ported to TB MIDI Stuff. There is also an editor for Patch Base here and free Edisyn 26 editor here. Without an editor it's like trying to paint a canvas through a keyhole.
