via this Reverb listing

"This FR-15 has a built-in button sequencer.

In addition to the 10 basic rhythms, up to 2 of the 5 sounds (BassDrum, SnareDrum, Cymbal, Claves, and Conga) can be played together using the 8-step button sequencer.

As the name 'RHYTHM PRODUCER' suggests, this is a point of difference from ordinary rhythm boxes.

The sound is different from Roland and Korg, and has a charming analog rhythm sound.

Made in Japan, this is a rare piece of equipment that is hard to find.

The following maintenance has been done.

Replaced a defective electrolytic capacitor in the tempo circuit.

POT cleaning and switch cleaning"

Bentley Rhythm Ace 60's Vintage Drum Machine

video upload by David Bessell

"Tips on how to work with vintage drum machines in a modern context. You can not easily just sample the sounds in early drum machines because they typically have just one mono out and little control over the individual sounds. Additionally sampling such analogue sources removes the liveliness and timing quirks that people like about these machines. Of course they also have no way of easily synching to a DAW although most DAW's can derive a custom tempo map from the audio they produce providing its close to the intended tempo."

4/10/25 Overloading an Alesis MIDIVERB II + ADR Pan Scan + SWTPC Psych Tone

video upload by Cfpp0

"I just posted a YouTube Short of the Multivox FR6M Rhythm Ace through the two Moog MKPE Parametric Equalizers, so this video is the last of the lower third rack tests after rewiring the patch bays. Some manual adjustments to the Pause Select switches on the SWTPC Psych Tone, which is running through the ADR Pan Scan, with some adjustments to the Pan Depth and Pan Speed. The Pan Scan outputs are hard-panned on the Mackie Onyx 1640 mixer. The Alesis MIDIVERB II is on an aux send and is fed a big dose of both channels. The MIDIVERB II blooms alone are worth the cost, but I love the way the MIDIVERB II overloads."

"Roland founder Ikutaro Kakehashi founded Ace Electronics in 1964, and this was one of their best products - later re-invented as the Roland TR-55. This example is re-badged Bentley Rhythm Ace for the British market (one of the few drum machines to have a band named after it). It has its original metal footswitch."

"This is a listing for the ACE TONE FR-15. In addition to the presets similar to the FR-6, this unit allows you to program one of the five sounds—Bass Drum, Snare Drum, Cymbal, Claves, or Conga—using 8-step or 16-step sequences. It has been tested and works perfectly. The voltage has been modified to 117V. The appearance shows some wear and scuffing, but there are no major damages. I have uploaded a demonstration video on YouTube, so please be sure to check it out."

"Here's a great sounding, all-analog, vintage drum machine from the 1970s that features some really great beats, incredibly warm and fat tones and a good amount of variation due to the fact you can combine any two of the different presets to create even more patterns as well as a variation knob that allows you to play the bass drum only, snare only and switches that allow you to toggle between 2 beat rhythms and 4 beat rhythms for even more inspiring variations. Your studio/performances need this awesome machine!"

1960s Fairchild 658 Spring Reverb / Ace Tone Rhythm Producer Dub Demo

video upload by foleytronics fx repair

"This is a Farchild 658 Spring Reverb, a very cool verb with a built-in optical compressor to achieve different reverb tail lengths. All three spring tanks are active at once, and they are positioned veritcally on the grey rackmounted panel. We used Mike's Ace Tone Rhythm Producer to test it after repair and I must say... it's a lot of fun.

The reverb was sold as perfectly working, but the compressor circuit had many faulty caps, two dead transistors and a burned out lamp. It's working great now!"

"rare analog drum machine from the 60s.

Basically it's almost 100% the same circuit as the Ace Tone FR1 / FR2L and as the Farfisa Melodic Rhythmer CER-60 in a different case.

Was also sold / rebranded by other manufacturers like NDK, Nomad or Goya, often in slightly different cases and different names but sharing the same pattern and cancel switches.

Unit was serviced: every electrolytic capacitors were replaced and unit was calibrated. Sounds and works as it should.
Cosmetic is in quite good condition except sor some minor scuff and wear."
