Electra One - Generative Sequencer preset

video upload by Electra One MIDI Controller

"A demo of Electra One MIDI controller running a generative sequencer preset. The preset is greatly inspired by the Zoa sequencer IOS app.

Roland MKS-50, D550, and Kawai K5000 play the sequencer voices. Sound of MKS-50 is tweaked while the sequencer is running."

Orac's Krell - demo of a new way to use Orac

video upload by TheTechnobear

"Over the last few months Ive been collaborating with Electra One.

They have recently made their firmware open source, and I wanted to write a custom firmware for Orac to allow a new way to interact with Orac running on any platform.

This video is of the patch I made for their booth at this years Superbooth (2021) , showing Orac running on a Terminal Tedium.

This firmware will also work on the rPI, Organelle and other Orac platforms.

The patch is a generative patch based on the 'Krell Patch', which uses continually looping envelopes that change randomly over time.
these envelopes are used for many aspects, including note generator, amplitude and also also various parameters affecting timbre and filtering.

This was implemented by creating new Orac modules that contained these new 'krell' envelopes.

a fun patch to just let do its own thing, and tweak as you go along.

(I also had the patch running on the Organelle-M at Superbooth)"

Jamuary #28 - Together we rock (ft. VCVRack, Eurorack,Soundplane)

video by TheTechnobear

"Today was all about trying to bring everything together....

The idea is simple, using the power of the computer (my little mac mini m1) to use the wonderful vcvrack, yet have it behave like an instrument with full hands on control.

Ive used vcvrack a bit in the past, but never really tried to integrate it fully..
the basics of the patch are simple.
- a couple of voices using instruo and vult oscillators and filters
- pianoteq (vst host) using a vult filter
- aalto (vst host)
- a mixer with a couple of sends to 2 vahalla vst reverbs (vst host)
- audio recorder to record the output
- midi to cv, to connect to hardware

the the bit thats Ive not done before... using midi mapping to map a controller.

on the hardware side.
the aim here was about hands on control...

the pyramid is used as the main sequencer and clock

the hermod is really the brains.
its sending the cv to the eurorack, midi to vcvrack, and its also taking cv/gate from the USTA to sequence vcvrack voices.

usta is a nice hands-on sequencer, quite different from the pyramid, more like an analog sequencer.

electra one [additional posts], lovely controller with encoders and is touch screen too - its easy to customise, so here I created a quick patch that controls vcvrack, things like levels, fx, and filters. once setup, I use midi map in vcvrack to assign controls.

the soiundplane again comes into play as the main playing surface :)

its was quite a lot of setup, but really just because it was the first time... so I had to decide how it was best to connect things, what role they would play.

its the first time my little mac mini struggle a little bit.
in fairness, it was fine whilst I was playing...no audio glitches at all.

but of course, as soon as I turned on the camera issues started appearing :)
the issue is I also had to run OBS to record the webcam, and quicktime to do a screen capture of vcvrack... that seem to just take it a bit over the top.

... which was. a bit frustrating, as I was getting tired by this point, and just wanted to finish... but I got there.

I might give it another go tommorow, now its all setup - so I can focus more on the music side , rather than cables and midi ;)


hope you enjoy

tech note: I should say VCVRack, plugins , OBS are all Rosetta , so I think we can expect them to improve. also honestly, Id have not even tried this on my old mac - its also possible the issue was related to usb traffic, given I have audio interface, webcam, monitor, soundplane, hermod, electra one ... alll sending a lot of data over usb ;)"

Electra.one is connected to Mac with a USB cable and ESI KeyControl 25 is connected to Electra's USB host port.

Three MIDI CCs are used to control Absynth 5's oscillator frequency, filter cutoff and resonance."

New Electra 4 x 4 Next generation Touch MIDI Controller

Demos with a Rhodes Chroma & TB3 Published on Jan 24, 2019 Martin Pavlas


A new programmable MIDI USB controller from Martin Pavlas of https://www.electrasid.com

"Electra is a fully programmable MIDI controller for studio or live rig equipment. The controller provides real-time visual feedback for up to 36 MIDI controls at once. Features high resolution 360 degree pots with touch sensing and a capacitive touch display. Extended connectivity offers USB MIDI device and USB Host interfaces as well as four DIN5 MIDI In / Out ports.

The driving idea behind the project was to make programming of Rhodes Chroma synthesizer easier. Chroma has got almost one hundred sounds parameters and editing them without seeing other relevant parameters at the same time affected the creative part of the process. Over the time, Electra has become an all-purpose MIDI controller with extensive USB MIDI interface and host integration.

The main concept of Electra MIDI controller is so-called Control. The control represents a MIDI parameter, its value, and assignment to a MIDI port and channel. An example can be, say, Cutoff frequency of Rhodes Chroma connected to MIDI port 1 channel 2.

A control visualizes value of an assigned parameter as well as it can modify the value either turning corresponding pot or with a touch gesture on the display. Watch the demo of control manipulation on youtube.

There is a number of control types: faders, dials, switches, buttons, and selection lists. All controls can trigger CC, SysEx, or NRPN MIDI message.

Controls are organized on Pages. A page is a set of controls that are displayed on the display at the same time. Pages may group controls by their meaning (Oscillator, Filter, etc) or can be collections of controls that should be close together for a performance purposes (Filter cutoffs and modulations of several connected synthesizers).

A set of pages is called a Preset. A preset is a top level configuration of Electra and consists all information about controls, pages, connected instruments, and MIDI routing.

Presets can be created with an Electra Controller Editor application and users can easily switch between them.

Electra EP-501 Sampler Delay demo

YouTube Uploaded by FOCtv on Aug 27, 2011

"Demo featuring the Electra EP-501 Sampler Delay. In Logic I'm using a preset beat from Ultrabeat. The EP-501 is being controlled by a MIDI-to-CV converter. Ultrabeat is being fed into the EP-501 which is sampling the beat. The pitch and gate of the EP-501 is coming from a MIDI track in Logic. The EP-501 takes a sample each time it receives a gate signal and loops it until the next gate signal."
