Turn your Atmegatron into a sci-fi dream machine

The Delayertron software is now available on the Downloads page of the Soulsby Synthesizers website.
You can see a video of the Delayertron in action here:
The heart of the Delayertron is a crunchy 8-bit delay line. The following parameters can be adjusted:
  • Dry/wet mix
  • Delay sample rate
  • Feedback
  • Delay length
  • Clip mode (for gritted distorted delay with >100% feedback)
  • LFO and envelope amounts to control the sample rate
There's also a filter which can be either high or low pass. The LFO can control it's cutoff and it can be inserted either after the delay or at the output mix.
All the oscillator waveforms are new too and have been increased from 32 to 256 samples long.  The waveforms are derived from Adventure Kid's awesome waveforms library.
The software can be uploaded by anyone who owns an Atmegatron and an FTDI cable.  See this video for instructions.

Only a few Atmegatrons left in stock!

It's been a crazy few months and we're now heading towards the end of the first batch. There's literally just a couple left! If you still haven't ordered your Atmegatron yet, head over to the shop.
A second batch of Atmegatrons will be made, but these won't be ready until later this year.
There are also some resellers that still have stock: Juno (UK), Analogue Haven (USA), Perfect Circuit Audio (USA) & Gizmo Music (Japan).

Pre-release version of Atpolytron software now available

Version 0.1 of the Atpolytron software is now available. It provides 4-note paraphonic polyphony to the Atmegatron. There will be some major changes to the software when the final version is released, such as longer waveforms and a different audio processing chain.
Also in the pipeline are:

  • Delayertron (simple synth with tape delay fx).
  • Envelopertron (not final name! Snappy logarithmic envelopes with envelope repeater).

And there's more that are just at the 'idea' stage, so watch this space!

miniAtmegatron development in progress

Here's a first look at the miniAtmegatron Arduino shield kit. It's at the prototype stage and is currently being debugged and tested.
The miniAtmegatron is designed for Arduino and electronics enthusiasts who want to build their own Atmegatron
It'll come with build instructions and also instructions on how to flash the Arduino to turn it into a USB MIDI device.
There are also plans to create a control interface with the Lemur iPad software.

Atmegadrum software released today

The Atmegadrum software is now available from the Soulsby Synths website. It turns the Atmegatron into a 16-part 16-step drum machine. It also features a global pitch LFO and individual instrument volumes and delay effects.

The default sample rate is a crunchy sounding 8kHz and this can be tweaked. Check out this YouTube video to hear it in action. There's an audio demo track on Soundcloud too.

In the near future there will be software to allow users to upload their own drum samples to the Atmegadrum.

Latest Atmegatron Reviews

If you've still not got an Atmegatron and want to know more about it, be sure to check out some of these reviews:

Soulsby Synths at Games Britannia

Soulsby Synths will be at Games Britannia Live! in Sheffield on 28th and 29th June. It's a family friendly video gaming and coding festival.

During the day there will be Atmegatrons out for people to play and visitors will have the opportunity to try sampling their own voice into the Atmegatron.

During the evening there is a "Chiptune Gig In The Garden". Soulsby Synths and _ensnare_ have teamed up and will be performing live. Be sure not to miss this!!!

Atmegatron Complete back in stock soon!

A limited run of Atmegatron Completes will be available in the second week of June. If you would like one of these please email the waiting list, as these have nearly sold out already!

Development is well underway with the miniAtmegatron DIY kit and Eurorack project. I hope to have more news on these projects in the next few weeks.
