Product Overview

Seventy7 is a virtual simulation of an old drum machine from the 1970s generally known as the Rhythm77 or TR-77. The TR-77 itself evolved from the Rhythm Ace and its original purpose was to provide rhythm to home or professional organists.

The sounds in Seventy7 are 24 Bit resolution samples with up to 8 round-robin variations depending on the sound. Great care was taken in recording and editing the sounds to get the best quality possible.

All the original rhythms have been accurately reproduced and can be combined together like the real thing. Seventy7 makes it easy to include these rhythms in your own music with its built-in performance recorder. Record a few bars of a rhythm then either save it as a MIDI file or drag it straight onto a track in your sequencer or DAW ready for playback.

Please note: You will need the FULL version of Kontakt 5.8.1 to load this instrument (NOT for Kontakt Player)

Fun, Quirky, Great Sound

As someone who never got to use an original TR-77 or CR-78, getting to play around with these recreations and not just some sample packs is the best - the functionality is really playful and sounds great to me!

I thin I bought this because Sade used it? I can't remember. :P Anyway, it is what it is, a great emulation of a very dated sound.

As an owner of a TR77 i am astounded at how good this emulation is. If you want an accurate reproduction of this vintage machine look no further than this.

punchy retro goodness

Good news! If you spent any time mapping your grid controller to the CR78 from forgotten keys their Seventy7 uses the same keys! This is another faithful rendition of a now rare machine. Round-robin sampling keeps it from sounding "sampled" and it's a joy to tweak both while using the internal rhythms and when feeding it your own midi sequences.
