Arturia Jupiter-8V Comparison Testing

Gavin sent the following into the AH list. I thought it was an interesting insight to how the test the accuracy of their models inside Arturia. I also thought it was an interesting challenge. So far no on on AH has taken him up on it. I asked him if I could put up a post here, and he gave the all clear. If you are up to the challenge, go for it and post back.

"Been a lurker on the list for a long time and am an analog synth fanatic also. In the day time, I work for Arturia and did the filter models for the Jupiter 8V. Since alot of people on the list have a Jupiter 8, I would be very interested if we could conduct some tests against the original, in the same way we do at Arturia to verify the circuit models accuracy. I can give you details of the procedure we use and do then you can do the same. Then it will be up to the list to decide."

"I have put up on the ftp at work some measures and audio files to show a small part of what we do pre-release or after each version build to make sure everything is working ok. I also included a read me file to show some tips on how to go about matching the Jupiter 8 and Jupiter-8V. These techniques would also be used for making the original preset banks. It would be great if some people could match up some presets as well."

Here is the link to a 7M zip of the files. I also mirrored them here.

EZ-VZ and The Casio VZ-1

Title link takes you to EZ-VZ, a resource site for the Casio VZ line of synths. You'll find the user and service manuals, the Powerplay VZ Book (picutured) and more. I actually have a VZ-1. I got frustrated with it today and went searching for the manual, which I almost never do. That's how I found this site. The VZ-1 is a Phase Distortion synth, similar to Yamaha's FM synthesis. It has eight source oscillators (sine, saw, and noise - multiple types of saw and noise) that you can have either act as a modulator for one of the other oscillators or a sound source, but not both. I had some spare time today and decided to just experiment with it. I rarely programmed the VZ-1 as I did not have a manual and every time I picked it up the interface held me back. Today I finally decided to give it a try and found it has one of the most horrendous design implementations in a synth. If you know of a worse one than this, feel free to comment.

So... It has up down value buttons and up down cursor buttons. Makes sense. You know how in most menu driven synths you select the group or page you want to edit followed by the cursor button to get to the desired parameter you want to edit followed by the value buttons to change the value? Well for some bizarre reason, on the VZ1 when you select the menu for the page you want to edit the value buttons let you flip through pages, and the cursor button does... nothing. Well it skips from page 1 to page 9, but what's the point of that? There is no way to get to the parameters to edit at this point. I spent about 30 minutes frustratingly trying to intuitively figure it out and finally gave up. I actually thought I might have corrupted the memory when I tried to us a PC editor with it. I finally went online and searched for the manual. It turns out, if you really, really want to edit the parameters, you have to select the menu again. WTF? The way it works is you select it once and at that point you can flip through the pages. When you get to the page you want to edit, you hit the same Menu button again and then you can use the cursor to move about the parameters for that page. To flip to the next page you have to back out of cursor mode by clicking on the same Menu button. When you get to the next page you want to edit, you have to click the Menu button again. Absolutely horrid and the most unintuitive design I have ever come across on a synth.

Once you get past this it does get a little better. There are buttons you can select to turn on and off the individual oscillators - one for each and there are buttons to select each osc for editing - figuring this out was a little tricky as well, but once I learned this it actually was easy and intuitive. Like any synth you just have to learn the interface, and unfortunately in some cases you actually have to crack open the manual. BTW, the VZ1, hands down, makes one of the most beautiful sine wave electric piano sounds. It's a bit more like a muted electric piano than a typical one. There's a certain depth to it that I have not heard on other synths. The eight oscillators running at the same time probably has something to do with it. The funny thing is this sound is actually the init patch sound on the VZ-1. Just add a little release and you are good to go. I'll be keeping my VZ1. For now...

Drumfire DF500

Click here for shots pulled via this auction.

Details:
"The Drumfire DF-500 is a 5 channel drum synth module. The 5 channels are identical, with their own Trigger-In and Audio Out sockets. Each channel is a mini analogue synth drum module, capable of producing a wide range of electronic drum sounds, and since every parameter is defined by a knob, it's highly tweakable. The 5 drum channels also have their own level and pan pots, and the signals are mixed to a pair of stereo outputs with Left/Right volume control.

Sequential Circuits Pr Fx Reverb

"This is a rare bird indeed. This is part of a modular effects system that Sequential Circuits developed in the 80's. This is a real reverb tank with springs inside."

via brian comnes.

Update via the comments:
"thats just the reverb tank.. you need the 518 MODULE to drive it... otherwise you just have a paperweight"

Update2:link
"The Model 518 Reverb includes a compact, rackmount six spring delay line, and a three-band equalizer which filters the input to and output from the reverb unit. The LP (lowpass) filter limits frequencies above its setting from 200Hz to 20 kHz. The HP (highpass) filter limits frequencies below its setting from 20Hz to 2 kHz. The MID (midrange) band filter has separate frequency (50 Hz to 5 kHz) and EQ boost/cut controls. For example a typical use would be to use the HP filter to prevent a bass drum from dominating the reverb. The module also features automatic limiting which reduces undesirable spring colorations. It contains a PEAK LED indicator for optimizing signal levels."

Title link takes you to the video. It's modular in design, in that you can build your synth by selecting filters, oscillators and other components from their various software. You can mix and match as you like.
