Superbooth 2026: WMD brings back the Gamma Wave Source wavetable oscillator in a new polyphonic version, and two-channel process modules.
The last day of Superbooth 2026 was 10 days ago, but I’m still receiving synth news that I haven’t covered. It’s been an incredible release year.
So also for WMD, which presented three modules in the Bungalow village, one of which is the Gamma Wave Source, making a comeback.
WMD Gamma Wave Source
In 2012 (+/), WMD released the Gamma Wave Source dual wavetable oscillator, and they discontinued it many years later. Now, the module is making a modern comeback.
The new Gamma Wave source, developed in collaboration with Nick from Infrasonic Audio, is no longer a classic wavetable oscillator.
It’s an entire polyphonic wavetable Synthesizer voice module with 8 voices, with MIDI, ART (Tiptop Audio), and 1v/oct/gate support. There are various voicing modes, allowing you to play it mono, poly, and more.
It consists of two wavetables (X/Y) with built-in wavetable modifiers like phase mod and interpolation.
According to Nick, it supports Wave edit wavetables with 256 samples per cycle and higher formats with 2048 samples from soft synths like Pigments and Serum. There is also an adjustable sub-oscillator with dedicated front-panel control and output.
Then, it has a filter per voice with a built-in drive and morphable outputs. On the modulation side, you have three ADSR envelopes per voice with hands-on slider control.
The module is operated with a main encoder, a few shortcut buttons, and a somewhat retro-looking display. I’m getting KITT Knight Rider vibes.
Channel Surfer / Bus Rider
Alongside the Gamma Wave Source, WMD also unveiled two new processing modules.
The Channel Surfer (CHNL SRFR) is a new 4HP Eurorack channel strip module for Eurorack. Neat, you can connect it to the Performance Mixer MKII via the insert header.
Alternatively, you can use it as an independent module in mono or stereo. It features a 3-band EQ with low shelf, high shelf, and a mid bump. The frequencies of all these are also adjustable with a press on the shift button.
Channel Surfer also features independent lowpass and highpass filters, each with adjustable resonance. An overdrive delivers extra character to the filters. On top, there is a multi-FX processor with a dub delay, a chorus, and ducking. According to Nick, more FX types will develop for it.
Bus Rider, on the side, is a 4HP stereo multiband EQ/dynamics processor designed for on-the-fly mastering at the end of your signal chain. It has a three-band isolator EQ and a lookahead limiter.
It’s also useful for submix and individual channel processing. The Isolator EQ is a great performance tool beyond fitting your mix to the room.
Both modules will save current states and have built-in presets that can be recalled at any time.
First Impression
Three exciting new modules. The new wavetable oscillator/synth voice looks interesting and sounds very promising. Anyone who owns the Performance Mixer MKII might be tempted by the new 4HP modules, as they nicely upgrade the mixer.
The WMD Gamma Wave Source is a prototype. Price and availability are TBA. Channel Surfer and Bus Rider are now available for pre-order at $299 each, with shipping in 3-4 months.
