The Groovesizer (http://groovesizer.com) with Alpha firmware is a DIY 32-step sequencer and synth. In this video, it’s controlling a Doepfer Dark Energy via MIDI. The video shows off the random pattern generation of the Groovesizer Alpha (major, minor, pentatonic, chromatic).
The Groovesizer (pronounced groove-a-sizer) is a DIY 8-bit audio platform. It’s a musical chameleon that can take on a number of different roles from sequencer to synth, drum machine, or midi controller. Exactly what the Groovesizer is at a given moment depends on the firmware it’s running. Existing firmware can be freely hacked, or new firmware developed using the beginner friendly Arduino IDE. Firmware is loaded to the board directly from the Arduino IDE, either via an AVR ISP programmer, or by flashing the Atmega chip on an Arduino board and swapping it out.
The Groovesizer is based around a custom PCB that features 6 potentiometers and 5 rows of 8 tactile switches and leds (4 rows for the sequencer / trigger buttons and 1 row dedicated to control functions). It features an integrated Arduino clone, an 8-bit DAC option, an LM386 amp output, MIDI in/out/sync and is configurable to work with some of the most popular existing Arduino audio projects.
Furthest along in its development is the Alpha firmware which features a 3 oscillator monosynth attached to a 32-step sequencer with 112 memory locations to store patches and patterns.
This track was created using a Step Sister, a Casio VL-1, Ibanez DM500 delay and an Inkel MX880E Mixer, details below:
Using the DM500 and the inkel mixer i was able to create a wide delay effect by running the DM500’s normal and inverted outputs into the mixer separately and hard panning and EQing them. Interestingly this technique isn’t mono compatible though so if you’re listening on a phone or tablet you won’t hear any of the delay due to phase cancellation trickery :O Another quicky this one as i’ve been too busy to do my weekly upload so i’m trying to catchup!
Right, so here’s the idea. Trying to write, upload and give away a fresh piece of music on a roughly weekly basis. Will i be able to keep it up? Will i run out of ideas? Can i be bothered? How shoddy will they be? Does anybody care? God knows. But that’s the point.
Basically the idea is to flex my musical muscles a bit. I have collected quite a bit of gear over the years and not much of it is getting used as much as i’d like, so this is my attempt to justify all those purchases whilst practising improving and getting ideas down fast as an antidote to procrastination. “Inspiration exists, but it has to find you working.” as Picasso once said.
Royalty free for you to use for whatever under the creative commons license. Just rip the audio out of the video for now, i’ll get these tracks uploaded to a dropbox account when i get my act together. Let me know if you use it, i’d be stoked.
This is RNInstruments 12×16 step sequencer developed with the Arduino.
The Korg Radias is a Virtual Analog synthesizer that was released by Korg in 2006. It takes advantage of the MMT (Multiple Modeling Technology) that their flagship OASYS synthesizer module employs. The synthesizer itself is similar in design to the MS2000, but offers many more capabilities. It is capable of emulating older digital synthesizers and classic analog synthesizers like the MS-series without any noise or aliasing. The Radias also allows for various external sounds to be fed through its filters and envelopes. It also has the Korg DWGS (Digital Waveform Generator System) that the Korg DW-8000 employs.
The Radias also takes advantage of the KKS (Korg Komponent System) which allows it to be used with the 49-key keyboard or used as a standalone rack module, and the Radias-R unit can be connected to the M3 Music Workstation/Sampler along with its various keyboard models.
The Radias has two oscillators per timbre and a noise generator. Oscillator #1 has nine basic waveforms, with four types of modulation and PCM (64 synth sounds, 128 drum sounds) and Oscillator #2 has four basic waveforms with two types of modulation. The Radias has the ability to stack up to five types of waveforms in Oscillator #1, while using only one voice of polyphony. In Unison mode, you can stack five additional waveforms, while using more polyphony. With this function, you can create some awesome super waveforms-the overall result can contain up to 25 detuned waveforms. The Radias also has two Low-frequency Oscillators (LFO) that add more modulation to the two audio oscillators. These LFO’s provide six waveforms and their speeds can be set manually or by tempo.
The Radias itself has four timbres per program. With a timbre, you can assign one drum program, another can have a lead, a bass, and a vocoder as well; all in one program! Each timbre can contain one synthesizer/drum kit, equalizer, and two multi-effects.
The Radias has two filters that can be used side-by-side, individually, or in a series. They offer Low Pass, High Pass, Band Pass, and Combination modes. Each filter offers 24 or 12 dB modes for the low pass filter. The effects on this unit are remarkable as well. The Radias comes loaded with 33 different effects: Delays, Chorus, Flangers, Compressors, talking modulator, and even the good old Polysix Ensemble effect. You can assign one master effect to the program, while each timbre gets its own two effects, creating a whole world of possibilities. The Radias also offers a 16-band vocoder with a nice Formant Motion recording function that allows you to record up to 7.5 seconds of external audio which can then be triggered via the keyboard.
The Radias has a built in arpeggiator as well, providing six different patterns to choose from. Patterns can be up to 32 steps long and the gate/velocity can be set for each step to get that sound you want! It also has two 32-step sequencers (they can be combined for a 64-step on a single timbre). They can easily be assigned to a drum kit, for example, to use the Radias as a programmable drum machine. The step sequencer supports 8-voice polyphony per step.
Orwell Digital has released the OR-1m Advanced Step Sequencer. The OR-1m is a sixteen-step sequencer with per-step controls for note pitch, duration and velocity. In addition, each step features four knobs for generating MIDI continuous controller data of the user’s choosing when each step is called.
The OR-1m also features MIDI remote control of all significant front panel controls via MIDI Controllers. Bi-directional MIDI control is also provided, allowing for MIDI control surfaces Behringer to update their displays when parameters on the OR-1m’s control panel are changed via mouse or preset recall. This allows users to experience the flexibility and performance of a computer-based sequencing solution while retaining the immediacy and feel of a hardware control surface.
The new Bias Channel allows users to easily offset the values of outgoing MIDI data without changing the settings of the individual steps. With a turn of the Bias Channel’s Pitch knob, all notes being generated by the OR-1m can be transposed up or down by single steps, or radically shifted over several octaves. Thanks to the OR-1m’s Force To Scale module, the resulting note output can remaining firmly in key. Similar controls on this channel allow for other MIDI output to be offset as well, including note duration, velocity and the four-per-step MIDI continuous controllers.
The Random Module allows all of the OR-1m’s step and loop parameters to have their values randomly generated within user-specified ranges, either individually or with all parameters as a group. Notes can be generated over a span of a just few pitches, or the entire multi-octave range allowed by the MIDI specification. Likewise, MIDI controller data can be limited in the values randomly assigned, which can be useful when a user needs to restrict the maximum resonance setting of a filter or similar parameter.
The OR-1m also introduces the concept of Random Locks. Present on each sequencer step and sequence loop, when activated they prevent their associated area from both having its parameters changed by the Random Module, as well as protecting from value alterations due to Global Channel changes. Another purpose for this function could be found when using the Random Module to repeatedly generate new note data, while periodically “locking” the steps which the user wishes to retain and protect.
The Loop section of the OR-1m features four loops, each of which has separate settings for the highest and lowest steps that will sound when the loop is played. Loop settings also include controls for section transposition and playback direction, including forward, reverse, alternating and random playback modes.
Any of the four loops can be selected for playback individually. In addition, all four loops can be played in sequence, allowing for the generation of extremely complex melodic lines and rhythmic patterns. When per-loop parameters such transposition and loop start step and end step are randomized, this loop-chaining feature can lead to very unexpected and often inspiring results.
The OR-1m also supports note-triggered sequence playback and direct-step triggering via MIDI Notes. Note triggering allows for the OR-1m’s sequencer to play its next step when a particular MIDI note is received. This allows for sequencers and MIDI instruments to control the OR-1m using a pattern of MIDI notes which could be quantized, to trigger the OR-1m with whatever “feel” the user prefers, or played live, allowing for all manner of realtime creative interaction.
Direct Step Triggering allows any of the OR-1m’s sixteen steps to be triggered when specific MIDI notes are received. This provides intense flexibility in playback order and allows users to intermix sequential playback with steps called out of their pre-defined sequence order.
The Common Channel on the far right of the OR-1m’s control panel allows for assignable MIDI controllers to be sent independently of the internal step sequencer. These controllers can be used to set the volume, effect mix or any other MIDI-controllable parameter of the unit or software receiving the OR-1m’s MIDI output.
The Force To Scale module allows users to make every note sent from the OR-1m conform to any of a wide variety of provided scales. Key can also be specified.
The OR-1m also provides extensive patch storage capability, with over 1024 patch locations available per bank. Banks can be easily saved to and loaded from disk.

Livid started some experiments with Max For Live step sequencers and the Livid Base. These are extremely rudimentary, but because they can be accessed with Device control, they are very powerful and easy to work with. Control of these step sequencers is as simple as pointing the controller to the device using the Base Remote Script for Ableton Live 9 in Device mode. One you navigate to a module, it acts as a “super device” handing off the pads and sliders to the Max for Live patch. While these little toys won’t be a “final” product, we’ll have something for you to play with soon!
Whatever you do today – you must listen to this machine – awesome sounds !!!!
