no i hadn't seen that yet- did a search of vids earlier this week (or was it last week?) and didn't come up with anything, so thanks!

so the "sync" button is hard sync on the mod osc from the main osc, right?

Here's a little teaser video. I slapped these together in about a 1/2 hour.
Really versatile and sonically rich! What you are hearing is coming from my iPhone mic. Some fun stuff with the CV controllable Waveshape switching of the Mod Osc beginning at 1:37. Thanks Roman! :party:

Thanks Todd, this is exactly what I needed to hear. Gonna get a friend build it for me. For sure.

I don't own a 259e, is the consensus that the 25s is more flexible than the 259e or vice versa. Also would you say it sounds better, similar or worse?

The 25s is a 200e style (aesthetic and size) version of the old 200 series 259/259r. So it's analog, and makes the same sounds a 259 would. The 259e is more of a digital wavetable-based module from the e series. So they will not sound very similar at all (other than some basic functional similarities. I also wouldn't use better or worse to describe them since they are so different. In fact, if you had a 25s (or 259/259r) AND a 259e, you would be capable of a VERY wide range of sounds.

Hi,

Anybody having problems with the principal oscillator? I bought two, and one of them works perfectly, but on the other one the volume from the principal osc is very low, and does not have the normal response of creating waveforms with high harmonic content by tweaking the timbre, symmetry and high order knobs. I've sent a couple of messages to Roman, but his email server might be down or something... :despair:

I received one, and it works well. Sounds like yours is faulty?

The comparison begins! I find them quite similar :party:
Be sure to listen to the Soundcloud audio file for true comparison. The video is just to orient you to what knobs I'm turning.

Please note: best to make audio comparisons from the soundcloud link above. The video was made via iPhone and the left speaker (25s) is 5-6' away from the right speaker (259r) which is 1' from the iPhone. Checkout the soundcloud for truer sound.

more to follow when I find more time . . . enjoy!

next comparison installment: Tracking and Pitch Modulation.
The audio file (L=25s/R=259r) is the one to choose for comparison; the video shows what I'm doing...

Thank you for doing this Todd. :nana:
They are really close but slightly different in some responses. I guess having both will makes one happy.

They seem almost identical to me - when you listen to the Soundcloud, it's really hard to tell that there is any difference.

I love the form factor of the 259, but the 25S means that you can realistically have the sound in a skylab case. A 259e, plus a 25S = a world of musical possibilities in a relatively small package. This is exceptional work by Roman.

Great videos (as usual) Todd, thanks for making these demos.

Having two of these in the same space as a 259r definitely seems appealing.

Listening blindly to the Soundcloud file, I preferred the 259r. Maybe I just like the sound of my right ear better.

Flip your headphones around and then randomly swap the channels in the file a few times ;)

Most people don't have the same frequency response in both ears.

Asked on another thread, but more appropriate here - would old skool Rogans work on this?

All the pots are the plastic D-shaft type. You could probably make Rogans work but it's possible they'd slip. I've never tried installing one on a D-shaft but maybe somebody else here can chime in.

Alternatively, if you're building the 25s from a kit you could source different pots.

not ideal,but works,the remaining gap you can fill in with some small plastic scrap material

To me this begs the question: how does the timbre/symmetry/order of the 25S principle compare to that of the 261e? Seems to be more apples-to-apples... :hmm:

What I did was to feed voltages, both (+) and (-), into the "high order" input. This makes the output much louder (otherwise it's markedly softer), and I can get enough harmonies to come close to a sawtooth wave. This is not the behavior of the other one, but they both have a much quieter output from the main oscillator. I find this behavior acceptable, as a little quirk in them, which honestly doesn't bother me much. They both sound great, and I can still get a beautiful sawtooth from the modulation oscillator. I don't want to ship it back to Japan just for this :doh:

I'm a happy customer with them as they are.... :nana:
