MP-2 + MRe: Hacking the Alesis Vortex and using a Wireless Midi Transmitter
A two-project merge! The Alesis Vortex needed a bit more… controls! So I decided to add a few sensors that would give me greater flexibility when playing. The Vortex is already quite capable, but my left hand was not “used” … Continue reading

MRe-2: A demo
I have decided to try the MRe-2 in a real setting. So I hooked up my keyboard and recorded a demo. It was done using Ableton Live 9. The trick was to setup 2 midi loops (using clips). The first … Continue reading

Midi Wireless: The iRig Midi adapter and Audeonic’s MidiBridge
In a previous post, I explained how I successfully use a pair of XBee radios to exchange Midi information between a midi instrument and a computer. This post is about another wireless solutions for those who have an iPhone or … Continue reading
MRe-2: XBee Midi emitter
In the previous post, I explained that I temporarily abandoned trying to use the RFM12B radio transceiver to exchange Midi information between two devices. This post explains how I successfully used the XBee radio transceiver to achieve sending information between … Continue reading
MRe-1: A special version of the MP-1: A Midi Transmitter
A special version of the MP-1 was built to get MIDI data from the Vortex and send it wirelessly to a computer for further processing. I have decided to name it the Midi Remote Emitter 1 (MRe-1). In fact, the … Continue reading

Jeenode: Interference
Because of the previous post, I decided to test a bit more. To see if I could physically move the board to reduce interference. So I connected the Arduino with the attached RFM12B radio module. The one using the Sparkfun … Continue reading
RFM12B: Dealing with radio interference
This is a screenshot from the serial monitor of a Jeenode (Arduino compatible) connected to my computer. It runs a program that will listen to incoming radio messages through its RFM12B radio transceiver. In this window, you can clearly see too … Continue reading

VC-1: New circuit
The first circuit design for the VC-1 was a bit unstable and very dependant on the quality of the control signal. Since the goal here is to control the resistance with a PWM signal from the micro-controller, the control signal … Continue reading
Tech Preview: Alesis Vortex (updated)
Update 16/1/31: The Alesis Vortex has been replaced by the Alesis Vortex Wireless . But the links below about in-depth reviews and complete user manual are still applicable and current. Update: 2012/12/21 – I am reviewing the Vortex in new posts. … Continue reading
VC-1: Volume Control Beta
The VC-1 is. On the left, the Silonex Audiohm opto-couplers (OC) with the electronic drivers. it has been described here. On the right, the line-buffer/impedance-controller described there. It works as expected, using two digital pins on the Arduino micro-controller to … Continue reading
