Description

The dukesrg/logue-sdk repository is a fork of Korg's logue SDK that carries several custom units by Oleg Burdaev (dukesrg), with the drumlogue sources on the drumlogue, mk2 and tsf branches. Synth units are FM64 (a 6-operator FM synth that loads DX7, DX21 and DX11-series voice banks, SY77 and opsix waves and logue wavetables as WAV files, with a converter on the project page), Tesseract (a 4-dimensional vector synth with customizable waveforms), loguePADS (a set of sample-based synths) and LogueTSF (an alpha-stage SF2 SoundFont loader for drumlogue and microKORG2, based on TinySoundFont, that reads .SF2 files from the Programs folder). Effects are Hyperloops (alpha delay, reverb and master variants) and Gator 2, a Kaossilator-style gate arpeggiator for delay, reverb and master FX slots that also runs on the NTS-1 mkII, NTS-3 and microKORG2. Vault is a program librarian unit for drumlogue and microKORG2. The FM64 unit file and manual are served from the project page; the others are zip files on the GitHub releases page.

Install notes

Download the unit from the project page (FM64) or from a release zip, put the drumlogue into USB mass-storage mode and copy the .drmlgunit file into the matching Units folder (Synths, DelayFXs, ReverbFXs or MasterFXs), then restart. Release notes for LogueTSF say to copy .SF2 files to the Programs folder.
