"A dry 1:1 comparison of the SonicProjects OP-X PRO-II virtual Oberheim VST AU software synth to an Oberheim OB-X Rev.2.
Both the OB-X and the OP-X PRO-II were recorded 100% dry and unprocessed over an RME Fireface UC - the OB-X over the line inputs and the OP-X PRO-II via optical cable over the optical S/PDIF-input. What you hear is the pure 24-bit recording. Of course there unfortunately will be some compression artefacts from YouTube.
Used hardware and software:
Korg MicroKey 37 MIDI keyboard
MacBook Air 2020 M1
macOS Monterey 12.1
Logic Pro 10.7.2
RME Fireface UC
SonicProjects OP-X PRO-II version 1.2.6 synth interface standard
Obererheim OB-X Rev. 2 with 6 voices installed
The exact detunings (deviating filter settings, warm up pitch drift, etc.) and the individual pan settings of the voices of OB-X have been copied voice by voice in every detail with the voice-based tuning features of OP-X PRO-II for a perfect match to the real synth.
To copy the bright sound OP-X PRO-II uses the BRL (brilliant) filter setting (DMP button, second button above voice mutes in the synth interface) which is dedicated to copy the sound character of the early OB-X and allows the filter to open into the ultra sound area and adds some extra shine in the heights.
The used patches are available in the synth's included banks library in this bank: Downloaded / PROII_COMPARISON"
Back with a 3rd Volume of Patches for the fantastic Moog One, demonstrating Patches 97 to 128. The Bank contains 128 Patches, which can be either Single, Split of Layered using all 3 Synth Engines.
There's a wide range of Sounds, especially Motion and Evolving Pads, Brass and Strings, solid Bass and Leads, plus a whole host of others.
Some of the Sounds are more experimental, however they all are playable and have Controllers assigned to the Mod Wheel, Aftertouch and X/Y Pad for maximum control of how the Sound evolves over time.
There can be only One...MOOG ONE - Singularity Vol 3.
"The Zerosum Inertia is a synthesizer in a pedal/desktop format that offers some
very interesting processing power for external signals. Thus unit can also be
used on its own with the external cv input to create melodic synth lines and odd
harmonic bass lines.
In this video we play the dry signal first and then bring in the BFK9000 for
crushing and processing.
"Loaded with New Old Stock JAN(Joint Army Navy) stamped 6CB6 pentodes designed to meet the high quality and reliability standards of the United States Military. Manufactured by Sylvania, Philips, Radio Corporation Of America, and General Electric in the 1960’s-1980’s.
Switchcraft jacks and Alpha potentiometers flown on wires and firmly bolted to aluminum enclosure to avoid stress applied to circuit board.
Circuit board attached to enclosure with standoffs again to reduce stress and tension being applied to circuit board. IC's are socketed, NOT soldered directly to circuit board to make easy replacement later if/when needed. High quality long life high temperature low impedance electrolytic capacitors from Rubycon and United Chemi-Con. 5% NP0 capacitors in the power section and audio path. 5% metalized polypropylene in the PLL sections. 1% metal film resistors. High quality 2A/25W medical grade 12v center postive DC power adapter is included. Only use 12v DC center positive power source included. Engraved enclosure(NO STICKER!!!!)
The BFK9000 is an effects processor designed to process audio signals from your modular synthesizer. VCO waveforms are an ideal source. Guitar will also produce interesting results. It is recommended that you patch your guitar into a preamp with an envelope follower before the BFK9000. Crank the gain and then patch the envelope out into the CV input of the BFK9000. The more gain you hit the audio input with the better the PLL's will track.
The higher the frequency the better the tracking.
Try cranking the PLL frequency to max then patching the output of the BFK9000 into a divider or pitch shifter down an octave or two. Patch LFO's, audio rate VCO's, envelopes, envelope followers, sequencers, random voltages, rhythmic pulses into the CV input.
Signal flow of the BFK9000 is 2 6CB6 pentodes providing gain to drive 2 4046 Phase Locked Loop chips behaving as primitive oscillators in parallel, but not wired up like a traditional PLL you may be familiar with. There is some conversation going on between the 2 4046's.....Something about an alien transmission of unknown origin scrambled with intermodulation and beating.
Frequency of PLL pitch and amount of PLL influence level for each 4046, 1 set on the left and 1 set on the right. Tube gain is maxed at full gain, no knob. 1 switch for each PLL that controls the behavior characteristics of each PLL."
"This Micromoog had been modified with lights and a clear face plate to show off the underlying circuit board. One of my all time favorite mono-synths. The ribbon, mod wheel, everything works. It needs a tune up though, would be a good idea to get the caps replaced. Cosmetically, it is in good condition. No major dents or dings to speak of. I have the original face plate but it has a crack in it. I'm happy to take offers or questions if you have either or both."
"In lovely condition, a few very minor scuffs as pointed out in the video.
Just finished servicing it.
All pots and sliders cleaned and re-lubricated (all sliders feel lovely and buttery)
New battery
Factory Patches Loaded
Thoroughly cleaned inside and out."
"Very little use, latest firmware, runs on Raspberry Pi 4B, faster and more memory than OG Norns. Ships with USB-C power adapter and 16gb SD card. The encoders are a little jumpy when turned quickly, and only on the PARAMS page, which I’ve learned is a common issue and can be rectified by editing the appropriate Lua file. Cheers!"
