The Behringer Proton
They cloned and improved their own Neutron.
From their Facebook page :
-
Paraphonic mode allows both oscillators to be independently controlled for multi-timbral sounds
-
Semi-modular design requires no patching for immediate performance
-
Pure analog signal path based on authentic VCO, VCF and VCA designs
-
Dual oscillators with 5 waveforms, oscillator sync, pulse width modulation and individual sub-oscillators
-
Oscillator waveform control blends seamlessly between 5 shapes (tone mod, pulse, sawtooth, triangle and sine)
-
2 self-oscillating, multi-mode VCFs can be configured in parallel or series with linkable CVs
-
2 ASR envelopes with reverse/inverse/loop/bounce options to control VCAs and wave folder
-
2 analog ADSR generators for modulating the VCFs for unique sound performance
-
Multi-mode wave folder adds rich harmonic content and massive flexibility to the LFOs
-
2 flexible LFOs with 5 waveforms, MIDI clock sync, key sync, phase and depth controls
-
Noise generator dramatically expands waveform generation
-
External audio can be summed into one or both VCFs to massively enhance sound generation
-
Utility functions include attenuverters, multiples, signal/CV mixer and summer for creative patching
-
External audio input with level control and soft clipping circuit for processing external sound sources
-
64 patch points for advanced modular connection and integration with external equipment
-
68 controls give you direct and real-time access to all important parameters
-
Complete Eurorack solution –main module can be transferred to a standard Eurorack case
-
Comprehensive MIDI implementation with MIDI channel and Voice Priority selection
ADDED ( 13 June 2023 ) : Expanding this thread the only way i can :
Comparing the Neutron and the Proton:
| Features | Neutron | Proton |
|---|---|---|
| Oscillators | 2 with 5 wave-forms | 2 with 5 wave-forms |
| Paraphonic and Sync Mode | yes | yes |
| Sub-Oscillators | 0 | 2 |
| Multi-Mode filters | 1 | 2 (series or parallel) |
| ASR envelopes | 0 | 2 with looping, reverse, inverse, bounce options |
| ADSR envelopes | 2 | 2 |
| LFOs | 1 with 5 waveforms | 2 with 5 waveforms |
| Wave folder | no | yes |
| Analog BBD Delay | yes | no |
| Sample & Hold | yes | no |
| Overdrive | yes | no |
| Noise Generator | yes | yes |
| Patch bay points | 56 | 64 |
| Knobs and direct controls | 43 | 68 |
I think it would be good to combine the two.
