video upload by David Hilowitz Music

Step is the first fully programmable drum machine in pedal format. It’s an instrument, a co-writer, an accompaniment at a live performance, or a bandmate in an empty studio. Designed with the flexibility to instantly start a unique song but with deep customization options to quickly create fresh beats. Step is for everyone – everyone that isn’t afraid to experiment, take chances, try something new, and create original music.

4 Customizable Drum Tracks
Step is a 4 track drum machine with a complete interface. Easily control all parameters for each of the 16 steps on the face of the pedal, no computer editor needed.

Mix & Match
How about an electronic snare with a jazzy kick? With Step, with a twist of a knob, you can create your sound pack by combining sounds from different Kits.

Instant Drum Beat Generator
Tap in the tempo, turn the Beat and Kit knobs to find your groove and play! There are 300 rhythms and 500 kits – it gives tons of combinations.

Modern Sound
With over 2000 samples, from the sounds of classic analog machines to acoustic drums, anyone can find the sound they

Finally a working polyphonic MIDI to CV converter with auto tune.

video upload by Craig Barnes

"I've been working on this polyphonic MIDI to CV converter for about 2 years. I've built several other polyphonic MIDI to CV devices, but I needed an 8 note 16 bit device for accuracy. So previously signals like modulation, bend, interval, detune were all generated on separate CV lines. This converter combines all signals onto a single wire for each VCO and filter. So in total there are 24 CVs generated, 8 gates, 8 triggers, 8 velocity CV's, plus 8 spare CV lines if needed.

The Teensy has a feedback loop from each VCO via a 16 way mux chip and during auto tune each VCO in turn is fed into the Teensy and the frequency of 8 notes from each VCO is sampled and corrected against the correct frequency. The difference is then stored in a table and the remaining 120 corrections are extrapolated from the 8 samples. These are then stored into the SD card and reloaded at boot time.

It accepts 5 pin DIN MIDI and usb MIDI or it can act as a MIDI host to a usb keyboard. I hope to make it the basis of an 8 note analogue polysynth that actually stays in tune.

Functions are controllable over MIDI

"Quick 80s inspired tune mainly to demonstrate the MIDI sync capabilities of the Tauntek MIDI kit.
(http://www.tauntek.com/Poly61.htm)
It's a basic MIDI kit that adds MIDI IN notes and Arp Sync control to the Poly 61, as well as MIDI receive channel. These features makes already a big differrence over a stock Poly 61, or over a Poly 61M which though has MIDI implemented only works in OMNI mode and don't let you sync the arp over MIDI.
All synth sound are from the Poly 61, drums and MIDI clock are provided by the Oberheim DX."

"6 voices analog polysynth, serviced and upgraded with a Tauntek Midi interface.

The upgrade lets you play notes over midi and also synchronise the built-in arpeggiator to MIDI clock !

Unit was serviced and is in fully working condition. It did suffer the classic battery leaking but was fixed and a brand new battery was fitted, along with factory presets.

Cosmetic is overall very good, except for the side cheeks that are damaged, and a key that was glued but barely noticeable, see pictures. Otherwise a very clean unit."

Watch as this song idea comes to life, showcasing the power and versatility of the MPC X SE.

RK-008 MIDI FX : The MIDI Delay

video upload by Retrokits

"MIDI Delay is an effect from 'Ye olden MIDI days' to emulate a hardware audio delay with a timed note repeat. You can change the note's velocity and note increment per repeat. And the cool thing: It's always synced to the beat!

In this video I combine with another new MIDI FX called 'Note 2 CC' Which can transform MIDI note messages and convert it to a value for a MIDI Controller (like filters or volume, .. ). It's a 'midi-event-converter' which is also used on the RK002/MOD firmware. An example is to add extra expression to various synths which do not have velocity response by default but you can also use it to for example play a volume gate pattern solely with notes.

There are nice effects on their own but can be combined to create something completely new - and - hopefully inspiring."

Vintage Soul in a Modern Body // GS Music E7

video upload by Starsky Carr

https://www.gsmusic.com/

"Drawing inspiration from the classics the GS Music E7 takes a 'best of' approach to bring us a modern VCO with a totally vintage vibe. It doesn't replicate any synth in particular, (it's got 7 voices for a start!) but you'll be familiar with all the functions and can recreate pretty much any classic tone. Talking of tones, it's got a wonderful sound quality that pulls you in and charms your socks off.

But it doesn't stop in the 80s.. we have MPE mode, it's 4-part multitimbral, with MIDI CC control, 600 preset slots, USB and full sized MIDI IN OUT & THRU

It also vas CV control for more sonic explorations - something I've not delved into yet."

Redshift 6 - Acid Tweak

video upload by Supercritical Synthesizers

"This demo tweak uses Redshift’s Sour character for its acid sounds.

All the patches in this demo song are made using one oscillator that is fed to the Sour characters 18 dB/Oct filter.

Pitch slides are programmed to the midi notes as pitch bend midi cc messages, and the note velocity modulates the filter cutoff through the filter envelope modulation.

Effects in this demo are all external effects."
