"Aaux card for the Buchla 208 / Music easel.

It's a 16 step envelope trigger module which offers drum computer like step input for two different Envelope outputs. Here a brief description:

- 16 three way switches, up selects output 1, down selects output 2

- Output is a simple envelope with only decay with a potentiometer and a CV input

- Length can be set to 16 steps or 8 steps, in which case it's basically a dual 8 step envelope trigger

- Sync input for syncing the Buchla 208 pulser to an external sync source

All in all a very straight forward card to use, but still a very complex card to build consisting of a 4 layer PCB behind de frontpanel, a 2 layer main pcb and a backpanel, sandwiched together. The 4 layer pcb and the 2 layer main pcb are connected via a total of 28 pins divided over 6 connectors."

BAF 2025: Buchla AUX Oscillator Card for Easel Series

video upload by sonicstate

"At NAMM 2025, we caught up with Nick from Buchla*, where he introduced us to the new *AUX Oscillator Card for the Easel series. This digital auxiliary oscillator card is designed to integrate with the 208 C revision of the Buchla 208 voice, featured on the modern and retro Easel editions, as well as the Easel Command.

The AUX Oscillator Card offers a host of features, including a CV multiplier for tenfold voltage utility, a random pulse input, and a noise generator. It allows for three-operator frequency modulation by supplying an additional oscillator. Nick explained that while it's a digital oscillator, the voltages interacting within the system remain analog. The card also supports a card doubler, enabling simultaneous use of the AUX Oscillator Card with other cards."

Elta Music Solar 42F - When the Ocean Comes to Swallow Us Whole

video upload by Thomas Carli

"Demo of a drone jam I put together on the Solar 42F. Nothing serious, but illustrates that while billed as an Ambient machine, can definitely venture into seriously dark territory. Hands down my favorite synth of 2024 and quite possibly the evil doppleganger of the Buchla Music Easel. No external effects used. Internal Infinity FX card on the Solar 42F the only effects featured. This drone uses the Hold function of several of the Solar 42F's Voices, the Arpeggiator on Voice 4, and manual control of Voice 6, as well as using LFO A to create additional modulation of the voice. Enjoy!"

Arpeggio on the 208 / Buchla Easel Sequencer Aux Expander Card

video upload by Roland Klinkenberg

"Mail me at rklinkenberg(at)gmail(dot)com for more info on the card."

"Card is back in stock and I made some small improvements:

- New PCB layout, easier to assemble.
- Trimmers for the 1,2V/oct adjustment (portamento) are reachable from the side. No need to take of the frontpanel anymore.
- Sequencer can be triggered by the LFO. This was already possible on the old card by moving a jumper. But now it's a switch position on the frontpanel.
- Envelope generator can be triggered by the LFO.
- Sync input Sync the 208's pulser to an external sync source
- Limited Purple edition ;-)

EDIT: everyone who's interested can email me at rklinkenberg(at)gmail(dot)com stating Buchla Aux Card in the description.
Price for a pre build unit is 400 euro ex vat(if applicable)

Here a description of the functions of the card.This is the new card (4 layer pcb with mostly SMD components)

- 8-step sequencer, clocked by either the pulser or the 208 sequencer’s switches. A switch for selecting 1 alternative step length (for example 7 step)
- LFO, 0.02Hz into audio range, with frequency CV input
- Portamento, on the CO or on both the CO and the MO.
- Envelope generator with ADSR, looped, and LFO modes, plus level control and decay time CV in
- And then some....see manual."

Buchla/Tiptop 259T | A Legend Revived

video upload by Cinematic Laboratory

"I don't think this module needs any introduction in Eurorack. Don Buchla inspired countless complex oscillators before it inspired Serge Tcherepnin and digital FM pioneers like John Chowning who brought FM on a chip to Yamaha. The 259 is a landmark VCO. One could assume it would old compared to modern gear like the DPO, Cs-L, Furthrrr, Brenso, Verbos CO and many more, but the 259 has a unique sound you will not find anywhere else.

There's 50 years between the 259c and the Tiptop recreation. A lot has changed. The original featured eight vactrols, but the T has none due to Hazardous Substance Regulations (RoHS). It's fair to say it's impossible to stay faithful. Autotune wasn't finished yet, it relied on the forthcoming 300 series that never took off. Remote/local control relied on Easel programming card tech which is useless in its eurorack incarnation. Tiptop decided to add ART support, a proprietary protocol which supports autotuning VCO's.

Real Buchla 259's are extremely rare, they're mostly faithfully recreated clones. So I had no idea how the real thing sounds and the 1M $ question is obviously 'does it sound the same'. Spoiler alert: it does. This video also concludes my 259 origin story, so it's episode 04 in the 259 playlist, and episode 09 in my Tiptop 200 series playlist. It's a bit confusing but it it makes sense to me.

Bottom line, it's a beauty."
