Actually, it has soft and hard sync from VCO1 to VCO2:

On the SH2/SH09 oscillator, I think part of it is the VCO design, but alot of it is how the VCF does or doesn't degrade the signal, depending on cutoff setting. I run my SEM oscillators through my modded SH-101's filter, an IR3109, which is a VLSI version of the VCF in the others mentioned, and can get something similar if the VCO output is hot enough.

Filters again, in this case that parallel fixed bandpass. It doesn't sound nearly as creamy if you take the VCF out of "VCF,BPF" mode. I love it too though. I'd sell my SEM and ditch my SH-101 in a flash if someone would sell me an SH-5 for a not stoopid price. Problem is, they are just too rare.
I know a certain someone on this forum who was using his just as a keyboard controller for his ARP 2600, and I was compelled to protest with righteous indignation.

I am no longer in pursuit of vintage synths. The generally absurd inflation from demand versus practical use and maintenance costs is no longer viable. The internet has suffocated and vanquished yet another wonderful hobby. Too bad.

Hm, then what's the main difference between the 5 and 7?

SH7 has a duophonic keyboard option, VCO1 has drawbar type octave harmonics for its square waveform, autobend, VCF is cascade lowpass and fixed highpass instead of multimode, first envelope is full ADSR instead of AR, more VCA performance options and retriggerable LFO's.

Thanks! If only I wasn't broke, unemployed and knee deep in debt atm! Curses, someone else is sure to snag it up quick!

And still people seem to want the 5 more than the 7? So it must have some removed features?

My guess is it's not the sum of features, but rather the tonal character of the 5 versus the 7. Clearly as has been reiterated in this thread, not all SH synths sound alike, in fact there seems to be a plethora of variety in that series.

The SH5 has an extra, non-cv controllable "magical" Bandpass filter.

This is largely the reason the 5 is more sought after.

I used to have an SH-7 and really didn't like the filter. I thought it was the weakest of the SH series... The organ drawbar type square wave osc isn't nearly as interesting as the waveform mixer on the SH-3A where you can mix different waveforms for each octave...

Both of these points are great to hear.

Well I love knowing that the SH-2 exists. It's important to come across a musical instrument that truly inspires you. We've all played plenty that have done nothing in this regard. When i do need to give this SH-2 back to it's kind owner, I will promptly seek to buy my own. It's funny cause this same person lent me an SH-7 for a while too, and although that thing was pure monster magic, the basic energy coming out of it was just too different than my musical personality. It was so satisfying to create so much juice with it though. Just for pure eye dilating space tangents. And i can attest to anything and everything people say about it. It is a huge alchemist.

For me I'm an meat and potatoes guy when it comes to synths. In other words, give me a truly wholesome oscillator sound and general core of capabilities and i'm set. I'm also not even that much of a filter freak. But the statements above do make me think that maybe i really am. I don't do much in terms of tons of sweeps and filter moves, but when i like what i hear, even when the filter sound is sitting still, i can't forget that it's indeed passing through a filter.

This is where great synth engineering speaks so directly into a musicians brain. Quality quality quality.

And no mention of the SH-1000 or the SH-3A?

If you want oscillator tone, go backwards!

Well hey Marc Doty. Great work you do, thank you for that!
Are those two pretty similar in discrete oscillator design/caliber/sound? Obviously the 3A is more versatile with all it's forms/levels but just wondering from your impressions how they both seem with tone side by side since you've gotten to do that. Of course this is an eye of the beholder thing too.

I quite enjoy that Rolands very first synth is something folks are after now.

The SH-09 is what got me into vintage synths after an impromptu demonstration many years ago. Had one since, and then traded up to a SH-2. Would love a Sh-5 and I considered one for a while but I just couldn't justify the outlay.

Just downloaded the service notes for the SH1 and SH2 and the VCO circuits and ICs are different for each, supporting your proposition that the SH2 VCO is different and therefore potentially better

I hade both an sh1000 (two of them) and an sh2 and the Osc. on the sh2 didn't have what the sh2 Oscs have.

sh2 definitely superior in that regard.

sh1000 had my favorite sample and hold tho of any synth I've tried

I've had an SH09 for a few years now and it has slowly grown to become my main synth. Layer in a little reverb/delay and I am lost for hours. The only thing I really feel it lacks is multiple independent VCO's for unison or intervals. But the PWM, filter and envelope are all just about exactly what I want in a mono. Nice little tricks like making the envelope only mod the filter, while the amp is just the gate make it VERY funky.
Most of the other Japanese synths I have played with over the years have a very cheesy filter quality to my ears. For whatever reason this filter just plain works. Right up to full on self osc it behaves well. I often wonder how ladder filter derived it is. It certainly gets nice and fluffy in a similar way.
It's also been my most solid synth. Even my T3 needs to be reset every now and then. And my DE's both get locked up by midi data if is too heavy.
Score one for non-firmware synths!
