Eurorack Drum Machine Update

Well, I’m making rapid progress. Have already built the frame for the Eurorack Drum Machine, based around a repurposed Pittsburgh Modular Cell 48 case, and installed three of the modules.

The Akemies Taiko and Pip Slope modules should be arriving early next week.

The Pico Trigger is amazing and really easy to program with the browser based pattern editor which works great from my iPad. 8 patterns can be stored in the module at any one time, even after powering off.

I particularly like the way that each of the 4 tracks has an independent length parameter (1 to 16 steps), great for programming polyrhythmic patterns that change over time.

The arcade buttons aren’t yet functional, but there is a DIY section on the Doepfer website which helpfully explains how to build a manual gate so I’ll start there; just waiting for some veroboard and a 6HP blank panel to be delivered first.

Also contemplating squeezing in a Synthrotek 555 LFO too to add some modulation.

Eurorack Drum Machine

Nearly finished with my rebuild of the modular synth. The Tiptop Mantis Case is full and I’ve also built a second suitcase synth based around modules from Mutable Instruments, Including the ‘Ears’ module which Santa got for me 🙂

So now I’ve turned my attention to building a portable, Eurorack based Drum Machine. Here’s a mock-up of what it could look like…

The core pattern sequencing will be handled through the Erica Synth Pico Trigg module, with the 5 arcade buttons at the bottom allowing me to manually trigger Accent and Choke on the two ALM Taiko modules as well as the Trig input on the ALM Pip Slope.

An ALM PE-1 rounds things off, doubling as a handy 2:1 mixer in addition to EQ duties.

Modular Update 2016 #2

The new rack is starting to take shape, but I have hit a bit of a snag! The case (made by Tip Top Audio) isn’t deep enough to house my Mark 1 Z3000 oscillator (also made by Tip Top Audio)! So it’s a good job I bought the Mark 2 version.

More selling on ebay methinks!

Also looking to get a Mutable Instruments Ears module soon to trigger my Rings module, as ably demonstrated in this video…

Modular update 2016 #1

Decided to have a major upgrade of my studio and also try and fully integrate the modular with my laptop setup.

First purchase was the Maschine Jam which has really renewed my love for Maschine and should elevate it beyond the role of ‘just’ a drum machine.

I then ordered some Expert Sleepers ES-40, ES-8CV and ES-8GT modules to let me trigger the modular from within Ableton, Maschine and Reaktor – only really scratched the surface but it looks to be a really flexible solution, and the integration with Reaktor is mind blowing.

Today, I took delivery of a new modular case, a Tiptop Audio Mantis, and it’s a beautiful piece of engineering for a brilliant price (at least, relative to other Eurorack cases).

Here’s the empty case which I’ll be filling up this evening as I transfer my modules across.

Also replaced my beloved Nord Drum with a Dinky’s Taiko drum synthesizer module too which I’ll be trying out later this evening. (I’ve multi-sampled the Nord into 20 or so Maschine kits, so still have access to its electro sounds – might even put those kits up for sale at some point).

Final piece I’ve ordered is a second Tiptop Audio Z3000 oscillator to compliment my old Mk1 module, which is waiting for me at the local post office.

Can’t wait to write some new music with it all!

Sonic Pi random sequencing

I bought a Raspberry Pi when they first came out, with plans to turn it into a MIDI arpeggiator or something similar. Like many of my ideas though, I never actually got around to doing anything about it so the Pi has sat in a drawer for the last couple of years, never once being powered on.

I then read a post on lifehacker.com about adding a mini touchscreen to it. A few days later, and I became the proud owner of an Adafruit PiTFT which has given the abandoned Pi a new lease of life!

This evening, I’ve been dabbling with Sonic Pi, a simple audio programming language that comes pre-installed on Raspbian.

With very little effort, I managed to get a nice, random sequence generator up and running in 5 lines of code:-

with_tempo 240
with_synth "dull_bell"
loop do
play_pattern [45, 50, 60, 72, 79, 84].shuffle
end

Version 2.0 of Sonic Pi is currently in Beta and promises to do a lot more than simple pattern playback including sample manipulation, more synthesis models and some effects processing too. Definitely worth checking out if you already have a Raspberry Pi and maybe an excuse to get one if you don’t!

Eurorack Lunchbox

My latest project, just so I have some modular fun close to hand when it’s too cold to sit up in my shed 🙂

Really pleased with the Spectre iPad sequencer too. Works great with the CV Pal module and allows me an easy way to program accents for the VCF303 via the second gate output.

Lunchbox 1

Lunchbox 2

Have some DIY modules lined up to build in the new year including an Alex & June filter and a Music Thing Modular Spring Reverb. Planning to mount the phono sockets on the side of the case so that the tank can be positioned away from the power supply.
