Testing revision 3 of a new prototype expansion board :)
Testing revision 2 of a new prototype :)
New TuuL Update available!
-It is now possible to ”fast scroll” parameter values, by pushing and holding an encoder, while adjusting a value.
-The “Release All Random Triggers” sub-chapter has been added to the user manual.
Longer lead times in July and August 2026!
For the past year, I have unfortunately not been able to sell enough instruments, to keep Gotharman's going as a full time employment.
I will therefore be out to check some job opportunities in July and August.
In that period, lead times on all products will be 3-4 weeks.
Email reply times and service times will also be affected.
What happens after this period, I don't know. I will do all I can to keep Gotharman's going for as long as possible, but it might be as a part time business in the future.
New Zaturn Zero Update available!
Bug fixes:
-After the latest update, the new sequencer triggers unfortunately blocked the EOC (End Of Cycle) triggers. Sorry about that! This has now been fixed.
-When the button keyboard was in locked mode, and Func or Steps were selected, and then when you went back to the keyboard, it would malfunction. Now only the hold functions are available on the Func and Steps buttons, when the keyboard is locked.
-Sometimes it would select the wrong group VCF. This has now been fixed.
-Sometimes it would play back the alternative parts, even though it shouldn’t, right after a preset change. This has now been fixed.
B-STOCK DEALS
Grab a great deal in our B-stock section!
New Little deFormer Zero Update available!
Bug fix:
-Sometimes when playing back a granular sampling or a wavetable, a click would appear.
This has now been fixed.
VCF8 Preset Set now available for Zaturn Zero
Discrete analog filters based on the Urano filters.
They have lots of character, and the character even changes, when the input level is changed.
At higher input levels and resonance settings, the resonance will distort.
They come with two 12db analog filters per group (8 in total), and each filter can operate in low pass, band pass and all pass modes. Inverted low pass and all pass are also available.
The resonance can be set to self-oscillating or non-self-oscillating.
TuuL Reviews
New Urano Update available!
-Compatible with VCF53
-Phazer and Allpass modes have been added to the Comb Filter effects
-Function Generator modes have been added to the Envelopes
-Curve parameter has been added to the Decay Envelopes
-A preset level parameter has been added
New VCF53zero Urano filter for Little deFormer Zero!
The filters on this filter board are based on the Urano VCF51, but unlike the original Urano filters, which were based on a filter chip, these filters are made entirely with discrete parts.
They have lots of character, and the character even changes, when the input level is changed.
At higher input levels and resonance settings, the resonance will distort.
This will add one channel of dual 12 db analog filters.
Each of these filters can be in LPF, BPF or APF modes. Resonance can be set to low or high mode.
Filter profile for LD3:
New VCF53 for Urano and LD3
The filters on this filter board are based on the Urano VCF51, but unlike the original Urano filters, which were based on a filter chip, these filters are made entirely with discrete parts.
They have lots of character, and the character even changes, when the input level is changed.
At higher input levels and resonance settings, the resonance will distort.
When used in Urano, one filter board will add 2 channels with each one 12db VCF. One of them can be set to LPF or BPF mode, while the other is always in LPF mode. Resonance can be set in low or high mode.
When used in LD3, it will add one channel of dual 12 db analog filters.
One of them can be set to LPF or BPF mode, while the other is always in LPF mode. Resonance can be set in low or high mode.

USB STICKS
Here you will find a list of USB sticks, that are tested to be working with Gotharman instruments.
In doubt which Gotharman's instrument to go for?
Then this Comparison List might help! -UPDATED NOV/2025!
TuuL and MIDI TuuL
12hp, 4 channel eurorack module with iconic Gotharman effects, oscillators, filters, modulation.
-4 completely independent channels!
-Each channel can be:
-Effects Processor-Iconic Gotharman effects! Granulator, reverb, delay, chorus, comb filter, compressor, EQ, pitch shifter, pitch shaper, phaser, sample pitch and more...
-Oscillator-Sine, triangle, saw, square, FOF, cymbal with many variable parameters.
-Filter-Dual or Vowel.
-Modulator-8 step modulator with rise/fall time and curve, hold time, level and ripples per step. It also outputs a random value per step. Can be trigged and synced to a clock.
-xVCA-VCA, Ring Modulator, cross fader.
Channels can be stereo linked!
Parameters can be randomized manually or by a trigger pulse!
30 memory locations!

AnaX USB
-USB CV expander
-Adds 4 CV/trigger inputs and 4 CV/trigger outputs to Zaturn Zero. Little deFormer Zero, Little deFormer 3 (MkI and MkII), Tiny LD (MkI and MKII), SpazeDrum and Zaturn (Analog and Digital).
-All modulation sources of the connected instrument can be sent to the 4 CV outputs (minijacks).
The output range is 0 to +5V.
4 LEDs will show the activity of the outputs.
-The 4 CV inputs (minijacks) appear as modulation sources, and it is possible to trigger parts from these. The input range can be set individually for each input to +5V, +-5V, +10V or +-10V, to match the sources.
-On Zaturn (Zero) it is also possible to sample the CV signals and convert them into draw waves, for further manipulation.
