Product Overview

Compu78 is a virtual simulation of the CompuRhythm CR-78, a very influential drum machine released at the end of the 1970s.

It features all the original sounds meticulously sampled at multiple accent levels and with up to eight round-robin variations depending on the sound. All the original rhythms and variations have been accurately reproduced and you can program your own rhythms in the same manner as you would on the original combined with a WS-1 programmer. In addition, you can record and save MIDI files.

It included several Snapshots that reproduce the rhythms of famous songs that featured the CR-78.

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

This recreation of a legend is so well done it is a must have if you love analog drum machines. Played along side of my real CR78 the software does such a great job of sounding just like its MASTER.

Does what it says on the tin!

Can't go wrong with this little library. Well sampled with a delightful interface. Easily the best CR-78 emulation on the market!

A brilliant emulation of a classic

This is an outstanding emulation of the Roland CompuRhythm CR-78. Easy to use, awesome sounding and brilliantly realised by a fantastic developer.

One of a (software) kind!

It seems amazing that only Forgotten Keys have done an extensive emulation of the CR-78, especially considering it's such an iconic drum machine (think Enola Gay & Fade to Grey and you get the idea).

In short, I feel like my search for the CR-78 sound and rhythms has come to an end, suh is the amazing job that Forgotten Keys have done on this, feature packed instrument.

I'm really looking forward to what else they come up with next

Maybe the closest plug to real thing

Perfect. Had the original one and this plug is so close to perfect imperfection of the original one !
Nobody can tell if it's the real one or Compu 78

A great upgrade to Forgotten Keys FK6

I couldn't pass this up. The original Forgotten Keys version of the Roland CR-78 was good. This is better.

Forgotten Keys nailed it !!

This is a killer rendition of a great hardware machine. I have owned the hardware for years, and its right there.... even better, actually. Big kudos for the great product.

Look no further

I have used a cr78 in the past and this is as good as it gets when it comes to recreating the original. So, so good.

Back to the 80\'s

Perfect for recreating so many early 80's songs from the likes of Ultravox, Visage and OMD.

great sounds, great looks, glaring functional omissions

I am a huge CR-78 fan, and I love the way the Compu 78 looks and sounds.

That out of the way, I find it very tedious to use. The only ways to make use of the presets seem to be to either "play it live" or "export MIDI files".

The most obvious way for me (only for me?) to use that thing would be to add MIDI key switches for start/stop and all the pattern selectors - that way one could just trigger the patterns with MIDI notes and save the hassle of dealing with the MIDI exports. Shame I don´t know how edit the Kontakt instrument myself.

Always the best

Forgotten Keys are one of my favourite developers from old drum machines, and as an owner of a real CR-78 I can say it's easier to use this and sounds like the real thing. I liked the old version so much I bought this updated version. The best CR-78 library out there.

dynamic retro sound

The attention to detail is evident when you listen. If you don't trust your ears you sample a bar of repetitive hits to any of the drum sounds and if you inspect the waveform you'll see the effect of the round-robin samples. Read the manual and you can learn how to export original rhythms from the machine (crtl-art + play button). Be sure to turn on the combine function so you can layer rhythms. Hint: be sure to set the temp to "host" by turning it all the way to the left.

Demo - Cold Dust of Space

The Compu 78 has a set of great presets of famous tunes that use the CR-78 (such as Enola Gay, In the air tonight etc.), so I used one of those as my starting point - I edited the preset a bit to include the famous 'metal beat' sound. The inspiration for the piece is John Carpenter soundtracks (more the ambience than a particular tune). He has very atmospheric beats in there (assault on precinct 13 for example), that remind me of what the Compu 78 offers. All the music is from Zom Zom by Synth Magic.
