WORLD OF MUSIC ; PORTABLE KEYBOARD - Latest Portable Music Keyboards, Synthesizers and Music News

Developer Andreas Remshagen shared this video demo of his free music sequencer for Windows PCs.

It is designed to be an alternative to hardware sequencers for controlling analog gear.

Here’s what Andreas Remshagen says about it:

“This is the Sequencer-Software I made with Flowstone (a graphical programming system) for my Live-Performances. It should run on every Windows-PC and is written to control Midi to CV-Devices like the Polyend Poly. It can Handle two different Devices with 8 Midi-Channels. Maybe you can use it for your own Performances.

It is completely free, so I don’t give a guarantee for everything.

If you have the Flowstone-Software you can edit the source-code-file called FL-Sourcecode in the Zip and change the Sequencer as you like!

This Sequencer works extremely stable in performance and Timing.

I normally work with analog sequencers but a Sequencer with the complete Functions like this Software-Sequencer would take up more space in my room than I have.”

Music Sequencer is available as a free download (.zip file).

Expert Sleepers has introduced Persephone, an analog Voltage Controlled Amplifier  (VCA) that uses a discrete Junction Field Effect Transistor  (JFET) as the gain element.

The JFET can be tastefully or violently overdriven for saturation/distortion effects.

Persephone also includes a zero-crossing detector, which can be used to restrict gain changes to zeros in the audio waveform, preventing clicks and pops that can occur with very fast envelopes, especially on lower pitched sounds. With the zero-crossing circuit engaged, you can use a simple gate as the CV input without clicks.

The module’s signal and CV paths are 100% analog.

Expert Sleepers Persephone is available now, with the following pricing: UK £159 (inc VAT), US $185 (exclusive of sales tax), EU €185 (inclusive of VAT)

midiphy has announced the availability of the MatriX Graphical MIDI Sequencer and Isomorphic Keyboard.

midiphy MatriX extends existing midiphy (or MIDIbox) sequencers with a large 17×17 button/LED matrix for graphical sequencing and more. The grid can also be used as an isomorphic sequencer to control your MIDI instruments.
