Dave Smith Instruments Tetra

Combo Patch Editor

This editor only works with the DSI Tetra. A Combo is essentially an extension of the standard (2-layer) patch to 4 layers, one for each voice.

Communicating with Edisyn

Set the MIDI channel to the same as being used in Edisyn. Set MParamSend to NRPN. Set M Param Rec to All or NRPN. Set MIDI Program to ON. Set MIDI Sysex to ON. And set MIDIParamLCD to ON.

About the Tab Names

Combos require many tabs; I apologize for the names, it was needed to fit them all on-screen on Macs. "Osc Filt 1" means "Oscillators and Filters 1". "Mod 1" means "Modulation 1", and "Seq 1" means "Sequencer 1". Likewise for voices 2, 3, and 4. Note the close relationship to similar tabs in the Prophet '08 / Tetra / Mopho single patch editor (which has layers A and B rather than voices 1, 2, 3, 4).

Parameters

In a combo, all four voices have (more or less) exactly the same set of parameters: however some parameters in voices 2, 3, and 4 have no functionality at all and exist only to make it easy to swap or copy voices. These non-functional parameters are marked with a [-].

About the Menu

The menu has several options that are useful for Tetra owners.
