Watching all my favourite bands on TV in the early 80's, the Prophet 5 was always standing out on stage, leading me to always wanting one... I still hope to one day get the Prophet 6. Thanks for this breakdown.

Korg or Behringer make good synths for a person who needs scratch an itch with a wallet that's a bit on the light side. Korgs 800 can be picked up for under 500 buck on reverb for a good example.

@@b00ts4ndc4ts Haha, Thanks! I did get the Arturia Prophet 5 VST and have been playing that on my Arturia keyboard, which lets me use the sliders and dials on the keyboard itself to adjust the VST parameters - certainly a big difference using actual tactile controls instead of a mouse, and I am really looking forward to my first real synth where I can do that for real.

Well it’s not a masterpiece of engineering. It’s a very creative insight, for sure. The execution of the engineering is home brewn at best. But that’s usually the case with innovators, they think outside of the box and basically prototype a working solution and others perfect the engineering. It’s easier to perfect someone else’s design than to come up with a design. But when I fixed one for a client I was amazed that a power supply like that actually would be allowed to be made. Same BTW with the AppleII, it’s like in America they have very lacks standards to mains power supplies. The only thing worse I found was 2 years ago (on this channel) a DDR chess computer I fixed. Only when I assembled it again, I read the print: “Netzzecker ziehen bevor offenen” aka pull the plug before opening 🤣I was like: “yeah luckily I always do that out of habit, but this could’ve killed you otherwise 😂” That actually also ran a Z80 but then a stolen clone.

Dave Smith was the man, there's no question about it. Not to be forgotten in the design of the Prophet are Dave Rossum and Scott Wedge of E-mu. They were design consultants to Sequential Circuits for the Prophet 5. They received significant royalties on the P5 Revs 1 and 2. The SSM synth chips in the Rev 1 and 2 were designed in consultation with E-mu. The Emu digital scanning polyphonic keyboard (designed by Scott Wedge for the eMu modular) was the basis for the P5 polyphonic keyboard.

Two books to cite here: "Musical Applications of Microprocessors" by Hal Chamberlain, and "CMOS Cookbook" by Don Lancaster... reedit: two books that allowed tom oberheim or dave smith too start using ssm chips, being later replaced by more "factory biased" and stable curtis chips, and achieve multiple voicing, and then be able to save voltage or switch settings. And yes "says a lot"; designing gear and reparing it is not the same task and often doesnt require the same skills and/or knowledge... love the channel btw.

I got yesterday a SCI Prophet 2002+ sampler from 1985 ( I got 2 in the 90´s). It shocked me for good that the PSU is magnetically shielded. Dave Smith was a genious, perhaps was to avoid the magnetical radiation deleting the diskettes. I got a friend with deep EHS electrosensibility who can´t stand being close to microwaves or magnetical radiation and I borrowed his measurer. I got more recent samplers as E-mu 6400 turbo that are not shielded, either any Ensoniq is. My Akai S3200 is also shielded. I never had any John Carpenter Prophet 5 but I love my Pro one and the Prophet VS. Rest in peace Dave.

I have to say, one of the biggest differences between this synthesizer and a modern analog polysynth... the number of green rework jumpers on that IC. In 2023, everybody has stuff like that on our prototypes. But in 1977, apparently Sequential did that on the production line (for at least 14 units)! I think that was much more common in the 1970s, 1980s, 1990s. Today, chips are a little smaller, so rework is a little slower, so it makes more sense to just spin the artwork.

In the late 70s, small business pcb were laid out by hand putting tape on clear polyester then photo reduced 4x to make the exposure masks. No computer aided support. PCB revs were costly, had long lead time and usually required you to permanently modify the previous version. So, you hand modified production boards to validate the design, burn down inventory and keep production running.

Yeah I agree with him. Analogue or mechanical instruments’ charm comes from being a few cents off and in affect being alive and changing - so much so that a few weeks back after a hot summer my guitar strings choked on the 2nd fret, took me playing two songs and wondering why I had to play it differently to realize that open strings didn’t ring out any more 😂 It gives it that innate modulation and the noise and hiss brings something too. I notice and hear when I play mechanical instruments what my mood and physical being is. When up strung up it sounds more aggressive the attack is harder. When I’m worn out or mellow everything is lighter and more controlled and you hear it too (or at least I think I do). It makes it more organic. And we can model this analogue imperfect on digital technology now to a T but it is ironic that in the 80s we went for digital to get perfection and now the most difficult part in DSP programming is getting that organic imperfection. Which sort of beats the purpose of digital in a sense 😂 But at least we don’t have hellishly out of tune oscillators anymore these days. In the 80s some synths were worse than Gibson Les Pauls when it came to staying in tune, and that’s saying something. 😂

I almost had a Prophet-5 but it got damaged during delivery. Though the previous owner was the "delivery service", that Prophet still hasn't tolerated its vertikal journey in its case from Vienna to southern Austria. Some parts inside got lose & VCO A turned silent. Luckiy I was refunded. Being still curious: Prophet-5 got replaced by creamware/soniccore PRO-12 ASB (beautiful desktop VA with wooden panel & an authentic Prophet-5 UI). Though it's soundwise not as authentic as Roland's Aira series, PRO-12 at least has 12 strong voices, Velocity and an always tuning stable Poly Mod. The latter is what it makes special & leads to unique, organic sounds, playable across the whole kb not possible with Prophet-5.

I had the fortune to fix one 4 years ago. The guy asked me how much does it cost. I said I only charge parts if it works and you’ll let me use it for a week. He agreed and I got to play it for a whole week. And I was amazed how similar my prophet8 actually sounded to the 5 except the 5 felt it had more fundamentals, really droning those low frequencies. But that was indeed a Rev3 looked very different. And in his case the only thing that was wrong was a regulator in the power supply. But that power supply was terribly designed. These days it wouldn’t be allowed on the market in Europe like that. Luckily back then there were no CE certifications otherwise we’d missed out of it. And the Z80 (MSX TRS80, Sinclair) was basically the standard CPU together with the 6502 (Apple C64)

Do not overlook the fact that if Dave Rossum at EMU Systems had not designed and licensed the parts that allowed for memory recall, and the voice, filter, and amplifier chips, companies like Sequential Circuits, Oberheim Electronics, and others would not have produced the products that they did. Dave Rossum and EMU Systems have often been overshadowed in the industry when it was them who helped start it all. Dave Smith and Sequential may have come up with some great gear, but Dave Smith's business tactics were not ideal and often morally bereft. Dave Rossum can attest to that.

I think the engineering of scanning the keyboard (licensed from the E-mu guys) was the real foundation of MIDI. Because that was half the work. You've basically got a MIDI message going to the Z80. But DCB on the Jupiter-8 ... that was an actual MIDI message, so maybe it was all Roland LOL.

Sometimes it's better to follow your ears. You try playing by circuit, you stop making music for people with ears. The tech is to inform your selection more than your use. I still love my old analog synths, but I will go for whatever makes the sound I am wanting. Amazing how often something like a juno 6/60/106 is just-right.

I had two. A Rev 3 and later a Rev 3.2. I never really liked either one. The sound was decent but the synth itself was poorly constructed IMO. The Pratt Read keyboard was sloppy and noisy and the gold J-wires broke quite often. I eventually bought an OB8 and never looked back. I still have it. I do thank Dave Smith for changing the synth world. His contributions to the analog world is immeasurable.
