Sunday Synth Jam : One Synth Jam session with Roland Jupiter-Xm


Sunday Synth Jam: Synthesist and sound designer Alba Ecstasy shared this one synth jam session, Tangent One, featuring the Roland Jupiter-Xm.


“This morning at 4:00am, I suddenly woke up and made this track on the Jupiter-Xm,” he explains.


The live performance makes use of the Xm’s I-Arpeggio function, which uses artificial intelligence to analyze your performance and create rhythms and sequences that react to your playing.


“The I-Arpeggio is amazing, offering me the drummer I always wanted,” he notes. “It’s like I’m controlling this drummer with my mind!”

Twisted Electrons MEGAfm MKII Synth delivers the sound of second-gen Sega Mega Drive


The original Twisted Electrons’ MEGAfm launched in 2020, was designed to put the FM sounds of the Sega Mega Drive ( Genesis) in an accessible hardware synth.


Now, we’ve got news that a new version MKII is on the way, and it’s based – appropriately enough – on the Mega Drive II.


This was a feature-tweaked, more compact version of the Mega Drive that was notable for using a slightly different iteration of the YM2612 sound chip – the YM3438. And, Twisted Electrons is following suit and putting a pair of YM3438s in the MEGAfm MKII, as well.


In addition, there’s a new circuit layout meaning that users can now access the sound chips simply by removing the bottom panel. In fact, you can even install alternative FM chips if you wish, such as the original YM2612, or custom variants. These can be mixed and matched.


Otherwise, the MEGAfm MKII is very similar to its predecessor, offering the same controls, audio circuitry and analogue distortion. The firmware is interchangeable, as well.


The MEGAfm MKII will be shipping in September priced at €564.

New Buchla-Format Algorithmic Oscillator is like Mutable Instruments Plaits on Steroids

1979 has introduced the Algorithmic Oscillator (AO), a Buchla-format VCO based on Plaits by Mutable Instruments.

The successor to the 1979 DAO, the AO has more knobs, more parameters, and more I/O than the DAO, plus features not available on the original Plaits module.

The company calls the AO “an ideal standalone voice module for small Buchla systems.”


  • High-fidelity digital oscillator (48 kHz, 16 bit)
  • 16 synthesis algorithms
  • Auxiliary output with complementary audio signal
  • Internal VCF/A with variable LPG mode
  • Voltage-controlled decay envelope*
  • Dedicated knobs for envelope decay and VCF/A amplitude*
  • Pitch quantizer (12-TET and Octave options)*
  • Inverting attenuators for all CV inputs (0-10V range)*
  • Envelope CV output (0-10V range)*

* Upgraded features not available on Plaits

The Algorithmic Oscillator is available now for $775.
