Amazing Jupiter-4 kit

[MrArkadin]

For €198 + P&P this kit is amazing. It really takes the JP-4 to another level: number of patches is increased from 8 to 32, you can now edit stored patches, send MIDI CCs with the sliders. Adds two LFOs.

You could now actually use this as a master keyboard.

- Faithful emulation of the original Roland Jupiter-4 programmer chip
- Memory is expanded to 32 patches and internally stored in non-volatile memory
- MIDI In and Out connections
- All 16 sliders and 9 switches send and receive MIDI control messages
- MIDI channel change from control panel (press MANUAL + PRESET switches)
- Modifying stored patches is now possible
- Sending and receiving MIDI Program Change messages
- Patch dump

Planned features:
- Firmware upgradable via MIDI
- Patch copy
- Patch morph
- LFO on any parameter
- Randomise parameters
- Elektron TurboMidi compatibility (10 times faster MIDI communication)

The second board is a usual MIDI interface that has the following features:
- Polyphonic MIDI Note messages
- Pitch bend control
- VCF control
- Volume control
- Portamento control
- Arpeggio rate control
- Firmware upgrade via MIDI
- Two MIDI-synced LFOs to modulate pitch and filter
- Pitch and filter modulation is increased to 10-bit
- Copy patch function
- A so-called second page mode to control added LFOs
- Arpeggio synced to MIDI

All these controls are parallel with the JP4 performance controls.

i can hardly contain myself, i loved my old jup, one thing i cant quite make out, is this a total synth replacement in its own right, ie buy it voila, upto date jup, or must you have an old jup that has to go to hospital, sorry to appear a bit thick,

Not sure what you're saying to be honest.

Basically you open your JP-4, disconnect some of the ribbon connectors, then the new boards connect where the ribbon connectors were and the JP's ribbon connectors slot into the new boards. All the original functions are still there, you're just adding another level of microprocessor control, updateable via MIDI. i'm not sure yet if there's a tiny bit of soldering but it's fairly self-contained.

Sounds exciting - thanks for the heads up!
