Launchpad Sequencer - Step Indicators

Just a quick update on the progress of the sequencer I'm building in Max for my final year project. I wanted the Automap lights along the top of the Launchpad to show which step was currently playing, so I used the counter object in Max to trigger a chain of objects that turn each light on and off in sequence.

Here is an overview of the patch itself:

Developing a Step Sequencer using Max - Introduction

My big project this year for university is to build a step sequencer using Max. I'll be using a Novation Launchpad as an external controller, and hopefully by the end of this I'll have built something pretty versatile that I can offer up on here to try out.

I found a great starting point on YouTube thanks to dude837. His Max videos are absolutely great, so I encourage you to check them out. His step sequencer project provides a brilliant starting point for me.


My initial focus is getting the launchpad to set cells in the matrixctrl object, so I've downloaded a copy of the Launchpad Programmer's Reference, which is available from the Novation Website. It gives a detailed explanation of the MIDI implementation of the Launchpad, and how you can take advantages of the various functions of the device.

I've laid out my project in a series of milestones, and for the first the sequencer must be able to do the following:
  • Store a simple polyphonic sequence of 8 steps
  • Receive messages from the Launchpad to set cells in the matrixctrl
  • Select different tempo divisions
  • Output correctly formatted MIDI messages
Nothing too ambitious to start off with, but the purpose of milestones is to implement functions sequentially. It also gives me a chance to get things working properly so that I can iron out any bugs as they come up, rather than leaving me in debug hell at the end.

MIDI Windchimes using Makey Makey

Ever wondered if you could use wind chimes as a MIDI controller? Well now you can, using nothing but cutlery, aluminium foil, copper strips, copper wire and a Makey Makey development board.

Home Made Ondes Martenot MIDI Controller (And Performance)

A truly fantastic idea here from an amateur instrument builder from Japan.

For those who don't know, an Ondes Martenot is an early electronic musical instrument that, as well as having a keyboard, had a ring that could be moved backwards and forwards along the instrument on a string, allowing for a very expressive performance.

CHOMP: The $50 Open Source MIDI Controller

I was checking my RSS feeds this morning and I came across a fantastic little bit of kit that an American high school student has built. It's called CHOMP (Configurable Hardware Open-source MIDI Platform), and he's currently trying to fund it through kickstarter. The best part about it is that it's only $50 US.


I've pledged $50, because I'd love to see this take off. I'd even consider buying a few of them if the project is a success. I like the idea of being able to build my own MIDI controller easily, and that's what this project offers; custom MIDI controllers without all of the hassle of programming your own Arduino board. That said, the production model will have a programmer header, so if you want to change the code you could do, as it is based on the Arduino standard. For instance, I contacted the project's founder, Max Justicz about using rotary encoders with CHOMP, and he informs me that with a small change to the code it would be possible to use them instead of regular potentiometers.

I just hope he manages to get it off the ground, it'd be a real shame if a piece of technology this useful wasn't a success.


Minimum donation is $1 US, and $50 will get you the board. If the project doesn't reach its goal of $25k then you won't be charged, which seems fair to me.

A Beginner’s Guide to Reason 5

Reason is one of the most commonly used music creation programs, and there are thousands of cool things you can do with it, but many people find it daunting when they first start out, especially when they’re faced with an empty rack. Today’s video shows how to set up your audio and MIDI hardware with Reason, as well as how to set up the basic devices you need to get started and how to select between different sound sources.
