The core is a M1 MacMini with 16gigs of unified ram and a 1TB disk. A Proteus 1, Roland SC-8820, Roland XV2020 Korg M1, Garritan Jazz Band, Garritan Personal Orchestra (yes, these work in Kontkat), and Kontkat provide the sonic palette in which I create music. M-Audio BX8a are my speakers of choice right now. Everything goes into either a Mackie DL32R, a Tascam 4×4, or a Allen & Heath CQ-20B.
Software I use includes Logic Pro X (I used it when it was on an Atari ST as Notator), Finale (LONG TIME USER, since…..the floppy disk days), Transcribe!, HX Edit, Eventide H9, ForScore, Musescore, Mainstage and Band in a Box (long time beta tester for them).
