====== MB-606RE ======

===== Introduction =====

The MB-606RE is a re-edit of CYM/HH and BD/SD drum parts of the Roland TR-606 to be controlled via MIDI (midibox MB-Modulbox) or CV through analog-Sequencers , in a a Eurorack-designed panel.\\
Well known Circuit Mods from around Web & time are included by default.\\

=== Analog Mods ===

  * **HH Noise:** 10K or 50K lin or log,have to check , orginally 10K trimpot,  only change volume not to absolutely silence.
  * **6OSC-Gain:** 50K log (not sure)
  * **CY-HH Ext:** 50K lin
  * **CY-HH BPF-Resonance:** 100K Stereo lin
  * **CY-HH BPF1:** 5K lin
  * **CY-HH BPF2:** 5K lin
  * **CY-HPF:** : 50K log
  * **HH-HPF:**50K log
  * **OH Decay:** 1M lin
  * **CH Decay:** 1M lin
  * **CY Decay:** 2M lin (internet) Phats machine has a 4M log

  * **BD Tune:** 50K Log
  * **BD Decay:** 2M lin 
  * **BD Tone:** 100K lin 
  * **Noise:** 50K log 
  * **SD Snappy:** 100K lin
  * **SD Decay:** 500K lin
  * **SD Tune:** 1M lin
