About a week ago I broke down and picked up a used Quasimidi Rave-O-Lution 309 that literally had been sitting on the same shelf in the same location for almost TWO YEARS! The 309 would just not sell at this particular used music shop I frequent. So last week I finally sat down and gave it a test drive at the shop and found it to be surprisingly quite good and fun. I asked the clerk if he had anybody interested in it and he said it was a very tough sell. The price was a tiny bit high which perhaps might have been the problem, but as a result of showing interest, he knocked the price down considerably to the point that I just couldn’t refuse. What I found out later after bringing it home was a bonus!!

Upon further research and inspection of the Rave-O-Lution 309, I discovered that the additional audio output section on the back was actually an audio out expansion board. I then opened up the bottom of the unit and found the OS version to be 3.00a. What excited me the most was to see both expansion slots filled!! My goodness, the Synth Expansion and Drums & Percussion Expansion boards where there.

Thus I soon discovered that I had purchased a fully loaded Quasimidi Rave-O-Lution 309. It even came with the original Quasimidi adapter. No wonder the price was a tad bit high to the casual observer. The original sales clerk who is now long gone probably did some research and priced the unit appropriately at the time. Unless you were “informed” about the Quasimidi Rave-O-Lution 309, you would never know there were expansions available.

After playing the Quasimidi Rave-O-Lution 309 for a while I soon discovered that this box really rocks loud!! There is a booster on it and when you dial it up a few notches, the drums really kick which is really great. I also found the on board sequencer to be super simple to program and create pattern loops. There is a MASSIVE glitch in the playback however after you finish a sequenced recording which is famously pointed out all over the internet. I’m afraid that likely will never go away since the product and company are pretty much discontinued. Thus you couldn’t really use the Quasimidi Rave-O-Lution 309 has a live looping drum machine, but that doesn’t matter really. You can create regular pattern sequences really fast and quite easily. Plus the multitude of knobs and ways to edit the sounds and grooves are fantastic.

Here are two VERY IMPORTANT links I found on the web that are required reading and downloading for the Quasimidi Rave-O-Lution 309. They are not that easy to find.

        70quid for each, synth+drum.its a good job they dont have akai written on them,the price would be 700 or somethin stupid,anyway, considering these are impossible to find nowadays 70 is a bargain.i also have oled displays,youll find them on ebay under quasimidi,the best mod on a 309 is replacing the old caps,i did mine+used elna silmic/cerafine, pana fm slimline where space was an issue.the end result was amazing ! + it cost peanuts !

    Do you happen to have photos of the audio expansion circuit board both front and back? There seems to be very few photos of these boards posted online and from the photos I have seen it appears there were 2 designs for the audio expansion board. I am trying to figure out what the differences are between the boards. One of the boards appears to have a couple extra capacitors added, guessing they made a second revision of the board at some point.
