Buchla 250e Dual Arbitrary Function Generator Tutorial & Demo

[@erixmix]

I came into this video with no idea what this machine was or what it did, I almost feel I could use one now. This is easily one of the best video tutorials I've come across on any subject. Thank you!

This helps a fuck load! The 250e is my most neglected module. Thank you!!!!!

[@DjNikGnashers]

I didn't have a clue what that module did. Your video is amazing, and explains exactly what every function of the module is for. Unfortunately I'm thick, and I still don't have a clue !

[@lilskullymane4057]

i really hope you make more of these, easily the best modular tutorial i’ve seen!

[@trickdigital]

Thank you! I do intend to make more soon.

[@lilskullymane4057]

@@trickdigital looking forward to it :)

[@mike.thomas]

Excellent. 100x more useful than the manual.

[@trickdigital]

Thank you! I'm so glad you found it helpful!

[@mike.thomas]

trickdigital Definitely! Mine just came in today, so I’m sure I’ll watch this vid at least a couple more times!

[@EaselCat]

More videos of this quality would be welcome and much gratitude would be sent your way sir.

[@trickdigital]

+Steven Bassett Thanks Steven. I a couple weeks, I'll be putting another video together. I've been getting a lot of requests for the 251e and the 252e, but I don't have those yet.

[@WeinglasMusic]

Great work Adam! Thanks for sharing this :)

[@memskew]

This is much appreciated; thank you!

[@trickdigital]

+Tom Martin You're welcome Tom. Cheers.

Thank you for uploading video !!

[@trickdigital]

I'm glad you like it! I hope it was helpful.

[@willwarden2603]

That thing is bat shit crazy I love it

[@JurekPrzezdziecki]

great! we need more!

[@trickdigital]

Thanks. More to come...

[@EaselCat]

Great video thanks.

[@trickdigital]

Thanks Steven!

[@rudetee]

Most helpful! Merci!

[@rhialto39]

This was really well done and very helpful. Why did you stop making these after just this one?

[@surrealchemist]

Well now I know what Suzanne Ciani was talking about when she mentioned this in comparison to the MARF. It can serve a similar purpose but in a live performance it might be lacking.

[@trickdigital]

Thanks Wein Glas!

[@maxrott3345]

great demonstration! is there any similar module in eurorack world?

[@trickdigital]

I'm not aware of anything like the 250e in eurorack.

[@6ood6ame]

Max Hasser have a look at the er-101 plus expander er-102 from orthogonal devices. One of the most interesting modules in the eurorack format.

Regarding stage addressing: I can't get my 250 to sweep through the full 0-16 steps. Best I can get is 0-14. Can you confirm yours does this?

[@trickdigital]

+ourigin. Yes mine does a full 0-16 stage range - but I’ve noticed some inconsistency, but it could either be from the calibration/precision of the 250e stage addressing itself, or the accuracy of the control voltage applied. For instance, when I first tested - not on the demonstration in the video - I applied from a source CV sweeping from what I thought was 0-10 volts, and the 250e would vary sometimes between a range or 0-14, 0-15 stages - but then later, with no other obvious factors, it would do the full range or 0-16. Perhaps this is due to either the 250e or the module providing the voltage not providing the expected range. I could have tested with a multimeter, but did not - instead I opted to run my source through a 256e CV processor to clamp and massage the source voltage into a range that would give me the 0-16 stage range in the way I expected. This gives me the most reliable result, as I don’t have to concern myself with the zillion other variables that might be affecting things: circuits warming up, small power inconsistencies/flucations, etc. that might be limiting the voltage needed to drive the full stage range.

[@ARBB1]

I can't imagine the circuitry behind this.

[@geot4647]

Seems like doing it with software would be much easier for presets, etc.

[@averagepainter]

man this is complicated. though very nicely explained, it still confuses me.

[@randyrankin682]

I want one but I'm not exactly $40,000 up right now... lol maybe someday

[@Auxar]

Nice video, thanks.

[@trickdigital]

Cheers.
