Mellotron M4000D Series

Sound & Update Cards

In addition to hundreds of more sounds, Sound Cards can deliver updates to your M4000D Mellotron Series instruments (Regular, Mini, Rack). Unlike many other modern electronic devices, the update only takes about 10 seconds. 

 

Sound cards firmware updates contain:

Updating from firmware 4.0 to 4.5

  • Note stealing - Digital Mellotrons have 10 note polyphony, which usually isn’t a problem. But if you use the sustain pedal and play 11 notes, the first note played is cut, allowing the “11th note” to be played. So the first note gets “stolen,” hence note stealing. 

  • Reversible polarity for sustain pedals

  • Improved MIDI functionality 

Updating from firmware 3.3 to 4.0

  • Compatible with sound card 04 which has continuous loop sounds

  • Motor emulation on high/low switch for pitch bend effect

  • Wobble level adjustment (emulates a wobbly analog Mellotron)

  • Store settings on sound cards 

  • Attack, release and start point can be set individually for each note on every sound

  • Two settings for MIDI pitch bend : +/-200 and +/-700 cents

Update your Rev 2 Micro Mellotron via Bluetooth under 1 minute with our free app!

  • On the Rev 1 the SD slot is between the Midi jacks and the Phones jack.

  • The Rev 2 Micro is the revision without the SD slot in the back.

  • This app is only intended for updating the firmware, i.e. operating system. It will not change the sounds of your Micro. The Micro is not designed to have the sounds updated, neither via SD cards nor via Bluetooth.
