Classic EML 400 / 401 Sequencer / Synth

via this VEMIA listing

"**NEW REDUCED START PRICE** EML 400 / 401 analogue sequencer and synthesiser Very rare, old and amazing! This machine is quite confusing, but when you get to know it you can see how powerful and unusual the sequencer is. The EML400 is the best vintage analogue sequencer I have ever used. As far as I can tell, it all works, but some of the sliders are crackly. Given its age, this is to be expected. Overall condition is very good, but please study the photos. The unit is 115V, but can include a step down transformer if requested. The user manual is available to download on the internet. Does require some knowledge to get the sequencer to loop. ***Plus VAT for a UK buyer.*** VEMIA can collect for packing (24GBP) or hand delivery."

"Super, rare original double-manual Prophet-10, in super cosmetic condition and with a wheeled flightcase and even a good number of Micro Communications Corp tape cartridges for the Exatron 'Stringy Floppy' - probably hugely collectable in themselves. Sounding great - just needing minor servicing - some of the contacts need a clean, and I’m not sure about the drive - not tested. The Program parameters are functional."

Serviced ARP Omni 2 Synthesizer Keyboard with New Sliders & Anvil Case

Note: links to listings are affiliate links for which the site may be compensated.


via this Reverb listing, also on eBay

"The ARP Omni-2 is a lush vintage string and polysynth famed for its rich ensemble chorus and analog bass section, delivering the signature 70s sound heard on countless classic records. With fully polyphonic strings, synth layers, and classic ARP warmth, it’s a must-have for anyone chasing authentic retro textures and atmosphere.

This synthesizer is in good physical condition and has just been serviced by Synthchaser in October 2025. Work done included:

Synthchaser Precision LED slider upgrade. New, smooth, high precision LED illuminated Bourns sliders. The difference in the way these sliders feel and perform compared to the originals is a huge improvement.

Recapped all polarized capacitors - including power supply and all tantalum capacitors

4075 Filter cutoff frequency correction

Keyboard refurbished - New key bushings installed, buss bar & key contacts cleaned and adjusted, keybed leveled, keys cleaned

Tuned & Calibrated"

Vintage ARP Odyssey Mk III 2823 Synthesizer Serial SN 28231528

via this eBay listing

"This vintage Mark III ARP Odyssey has been in my possession since 2017. It was serviced in 2019 by Jareth Lackey at SynthPro Restorations. In addition to being thoroughly cleaned, the unit's power supply was replaced, it was recapped, and the low audio output jack was converted to high level. Cosmetically, the unit is in remarkably good condition for its age. The steel chassis and leather side panels have been well taken care of and show very little wear. For the most part, the sliders work smoothly. None of the sliders offer that terrible sticky resistance often associated with vintage ARPs. The switches all work perfectly. VCO 1 probably needs to be calibrated, as it seems to frequently go out of tune. However, once the unit is powered up and left on for about an hour, it works fine. Also included is a custom soft-shell case that's quite sturdy and offers lots of padding. The original ARP Odyssey Owner's Manual and Patch Book are also included."

2025/10 - 1010Music Lemondrop realtime CC playing


video upload by Stereoping

"A realtime session on the Lemondrop granular sampler being controlled by Midi CC with a Synth Controller. Bass, tabla and drums from MPC One. I simply love to manually travel through a sample having the playhead position directly on a knob - especially if it's a voice or the sample contains different chords.

BLACK parameters are always available. The three color layers are distributed to RED for GR1 settings, GREEN for GR2 and BLUE for FX, Envelope1 and OSC Pitch.

Filter is set to PER OSC: GR1 runs through Filter 1, GR2 though Filter 2. Both samples are set to playmode FIXED. If MOVING would support the playhead to run backwards if the modulation becomes negative this also would be fun to play with. But currently it's only stopping when receiving -100% modulation.

Important: at the time i shot the video (2025/10, Beta V1.2.26) the Lemondrop does not offer default CCs. All CCs are manually learnt by hand. Means: changing to another preset stops the remote editing from working - until you learn them all again :-) Hopefully 1010 Music offers an update supplying a default CC scheme in the future. Until then it does imho not make that much sense to offer this LEMONTREE edition for the Synth Controller officially. In the 1010music forum there is a capable guy offering a free webservice to convert all presets to supply a special CC mapping but i did not try it yet. Still learning about this funny little sampler."
