free book disassembling the rev2 presets
« on: April 03, 2018, 01:12:51 PM »
Hi all,

Let's be honest: Rev2 is a monster. And monsters can be hard to tame.

Factory presets show a lot of what can be accomplished using the synth, but understanding exactly how/why they work is a challenge. Yes, I'm aware of the "compare" button and several software interfaces but in real vintage style (I didn't get an *analog* synth for nothing, right?) I felt the need to have a book.

So I sat down and made one, reusing, amongst other things, some formidable work done by DSI forum users Razmo and Gerry Havinga. And you, dear reader, get to download and read it entirely for free! Officially the best known way to explore your synthesizer in bed! It shouldn't come as a surprise that the book turns out to be a monster too, counting way over 1000 pages (don't print this at home, folks ::) !).

Since this is a first version of the book, it may have flaws, critical omissions, etc. If you happen to find such errors or  omissions, please be so kind as to report an issue to me, as described in the first pages of the book, on https://github.com/shimpe/sc-prophet-rev2 This is also the web address where you can suggest code changes or spec sheet template changes.

This book will always remain free under a creative commons license. Future updates to the book - if any - will be announced in this thread.

Note that the software I created to make this book is available for download too, and it allows you to automagically create similar sheets for your own REV2 patches, but at the moment it's not (at all!) user friendly - i.e. probably usable for hardcore tech nerds only (and unfortunately I have deadlines for other projects which means this situation will not change any time soon). If you do try and use it however, but get stuck, be sure to reach out, and I'll make a reasonable effort to help you figure things out.

In the mean time, I hope you will find the book as intriguing as I do!
For your convienience here's the download link: https://github.com/shimpe/rev2/releases

Enjoy!

Wow great work — it being April 1st I was half expecting 1000 pages of the scratch patch!

Hah! Turns out it's an easter egg after all. Turns out there's a problem in the software leading to wrong numbers in the "amount" of modulation in the mod matrix. Sorry for getting false hopes up. I will do my best to fix it as soon as possible. This is my punishment for spending more time playing the synth than actually testing the software :s (You have to admit it's a monster synth :D )

Brilliant work, absolutely amazing and automagically - even better. Now I have a good reason to audit all the factory patches I haven't listened to yet. Thank you!

Better wait until I manage to fix the problem. It turns out to be a bit trickier than I anticipated. The devil's in the details :)

Rejoice! For a new version of the book has landed with many fixes: https://github.com/shimpe/rev2/releases

Sorry for the inconvenience caused by the errors in the previous version. Although the new version is improved, there's still room for errors, so if you notice something odd/wrong/missing, feel free to log an issue.

- wrong numbers shown in modulation section (and some other sections)
- wrong numbers shown in track 4 of gated sequencer
- missing pressure controller in template sheet

You definitely want to get the new version from https://github.com/shimpe/rev2/releases !

(Edited to add: it'd be great if a moderator could remove the old link from the first post, as the google shortener service is designed to preserve all content it links to forever...)

It has come to my attention that in the previous version of the book,
the 4 pole/2 pole selection was not shown correctly.

Great work, thank you! Wondering if it wouldn't make more sense for you to include a compiled PDF as part of the commit for each change on GitHub so you don't need to keep updating Google links?

Also, could you include a blank spec sheet at the end of the document so we can copy it for our own (handwritten) patch notes?

GitHub doesn't really like uploading big binary blobs, but I figured 11MB was not too bad, so I created a repository with the latest version here: https://github.com/shimpe/rev2/releases . If you have/create a github account, it's possible to follow the repository and be alerted whenever a new version is pushed.

Hurray! There's a new version of the book that fixes the following two issues:
#6 sync checkbox appears too high
#7 missing arp range, repeats and relatch information

As a bonus, the download now includes a separate text file collecting some tips&tricks from the forum
(annotated with the author of the tip - please let me know if it contains errors or if you have things to add!).

As usual, get it here: https://github.com/shimpe/rev2/releases

You will want to click one of the links that says "Source code" (which, despite the name, contains a .pdf file and the bonus text file; the real source code can be downloaded per the instructions in the book itself).

Happy analyzing!

Thank you so much!! Just picked up the Rev2 and I am a newbie in analog synths. This is really helpful in learning how certain sound was created
