since the Sinfonion project has been moved from Instruo to ACL (Audiophile Circuits League) I think it makes sense to start a new topic for the final version of this module. I invite you all for discussion and questions about the ACL Sinfonion here.
Here is a summary of the technical changes to the module in the move from Instruo to ACL:
1. For sake of flexibility the dedicated CV jacks for MODE and DEGREE have been converted into the two assignable CVs "CV3" and "CV4" (which can also be assigned to MODE and DEGREE of course)
2. The CHORDS section now has a new button "13TH". That way you can create any arbitrary chord from the current scale with up to four voices.
3. The ARPEGGIO now also has dedicated buttons for 11TH and 13TH. The functionality of the less important buttons SYNC and BEGIN have been combined into one button in order to save one button.
4. The button layouts of all five sections - including channel 3 - are now identical. This helps live improvisation a lot.
5. Last but not least we got two new pots POT1 and POT2, which can be assigned to all CV functions where this makes sense. So manual wiggling of such cool CVs as "chaotic detune", "harmonic shift" or "chords bend" does not need an external CV module nor wastes one of the CV inputs.
6. Alas - the module size has increased from 38 to 42 HP. Sorry for this. But the musical neccessity of the two additional buttons and the benefit from the two pots was so great so we could not resist.
Here are two mockups:


For what the face plate concerns: I know that not everybody of you is a fan of grey as opposed to black. Yes, the black Sinfonion looked really cool. I very much like the design of all of Jason's modules a lot. But I also found myself liking the sober, technical, industrial style of ACL more and more. Maybe it's the understatement that is appealing to me. And Martin from ACL has done a really great job in reinterpreting the Sinfonion in ACL style! Anyway - this change of color is just a coincidence and not the reason for the transfer to ACL

Last but not least there will also be an increase in the price. I know that the new estimated price of 960,- EURO is a lot of money. I can understand everyone of you who thinks twice before spending so much money on just one module. But quality has it's price. The ACL Sinfonion will be manufactured in Germany - also the population of the PCBs. ACL explained to me that China is not an option for them. Even if their low prices are tempting - you can never be sure that they really mount the high precision parts that you have ordered.
And you can be sure that one Sinfonion is still much cheaper - both in money and in HP - than a bunch of loosely coupled quantizers and chord generators that try to mimick even a small part of its functionality.
For my part I am really looking forward to the time when the Sinfonion finally will be made available to all of you that are waiting for it and get all of your feedback - may it be critical or enthusiatic!
