TubeOhm Effects refer to the digital signal processing (DSP) algorithms and hardware modules designed by TubeOhm Instruments, spanning across their legacy VST software plugins, standalone effects bundles, and recent DIY hardware synthesizers. TubeOhm’s effects philosophy balances a gritty, vintage character with flexible DIY capabilities. Hardware DSP Effects (The Jeannie FX Board)
The most prominent modern hardware iteration is the built-in digital effects processor found on the Jeannie DIY Synthesizer .
The Core Hardware: The FX board is built on the popular Spin Semiconductor FV-1 DSP chip combined with a PCM 5102A stereo 24-bit converter (output limited to 16-bit).
Adjustable Clock Rate: Users can manually adjust the clock frequency between 10 kHz and 60 kHz. Lowering the clock frequency intentionally introduces lo-fi digital grit and “dirty” texturing.
Factory Programs: Includes standard algorithms like Chorus 1, Flanger, Tremolo, Pitch Shift, Pitch Shift/Echo, Reverb 1, and Reverb 2.
TubeOhm Custom Algorithms: Features 8 unique pre-programmed algorithms including X-Delay, Chorus 2 (5-stage), Tonator, Phaser, Flangerator, Distorter, Stereo Echo/Reverb, and Gate. Legacy VST Software Effects
Historically, TubeOhm developed standalone effects processing bundles and dense internal effect sections for their software synthesizers:
T-Xciter: A mastering and stereo utility plugin featuring dual harmonic generators tailored for emphasizing deep bass and high frequencies.
N-Gate: A dedicated noise gate featuring independent gate-on and gate-off threshold parameters to control signal spikes during the release envelope.
Instrument FX Engines: Legacy virtual analog instruments like TubeOhm Gamma-Ray and TubeOhm Alpha-Ray
integrated dedicated multi-stage polyphonic overdrive, tempo-synced delays, and specialized “Oil Tank” or “Poly Space” reverbs directly into the synthesis signal path. Pre-Filter Signal Shapers Wavebooster WB-03
: A dedicated DIY analog tone control network that alters the oscillator signal before it hits the filter. It provides separate bass, midrange, and treble boosts or cuts alongside an integrated overtone saturation/distortion LED circuit. Are you looking to build the Jeannie DIY synthesizer kit
