Btw… what are actually the use case for the inputs? How can you use them? 
The inputs are mixed in and processed by the filter. So anything that is done to the filter will apply to the external inputs.

I loved hit work on Hitman 2. 
He also scored MDK 2, Messiah, Splinter Cell: Chaos Theory, Kane & Lunch, Assassin’s Creed, Borderlands and Darksiders, as well as the excellent movie Tumbbad from 2018. Talk about a demoscene artist making it big!

Chaos theory, borderlands and AC all have some of my favorite soundtracks of that era - interesting to hear that they were all composed the same person!

I finally got my SidMKIII!
I have two orginal 6581 chips installed.
somehow I can’t acces fatmode F5 and F6, not sure what the problem is. I understand you need to be first in paraphonic mode before F5 and F6 reviel themself.
Screenshot page 6 from the manual: https://www.twistedelectrons.com/_files/ugd/b8c32b_6d9293361a4a4f2cb755ea67dca212bd.pdf
On the website you use the tool in order to acces the synth ( only blastbeats, megaFM and TherapSID) Both my TherapSID and MegaFM are nog reconized.
It needs to be detected as shown here: ( screenshot from the manual)
Here you see my Roland SP-404MKII MIDI connected to the SID,
It say’s it needs firmare 2.4 or above, with is currently 1.9. But because it won’t dectect the synth I can;'t continue
Any help or advice is more then welcome 
Yes, you need to update it to the latest firmware before you can use the web tool. So download 2.4 from the website and install as mentioned in the manual (hold down Filter on power-up etc, then run a sysex sending application on your computer).

Thank you Thomas for the lightingspeed reply!
I tried to install the update, using MIDI-OX but It won’t install it, did all the steps as stated in the manual, I’m able to boot it up, with the filter button and power-up button, all led lights lit up.
Tried to send the sysex, but I think it’s not reaching the synth?
I’m aware of the 64 buffer size, but so far no luck.
I’m using a PC, do you also use MIDI-OX?
Allright I finally made it to work, by updating from V1.9 to 2.4 I finallay have acces to fatmode F5 and F6. The problem was that I had to manual select in Midi-Ox the Midi in and Out.
finalllyyyy!!

Real rookie question, but… Can the the ArmSID or BackSID be used in the TherapSID? And if so, how do you set the internal DIP switches in the TherapSID synth? I know that it takes the Swinsid, but I have read that ArmSID and BackSID are better emulations when you don’t want to hunt for functioning originals.
See the post just before your, I gave the answer there It is not released yet, but will be soon. With that, the DIP switches can be set to any 6581 or 8580, because the ArmSID emulation is configured using the web tool instead.

I have been watching your vids - and they sound amazing. That said, I am still learning the absolute basics with the instrument. I have one on the way but without the chips. I am looking to purchase some soon so that I can get the TherapSID up and running soon. I just wasn’t sure how to set up the DIP switches inside the unit when not using the actual 6581 or 8580 because there is nothing in the manual about it.
Being in the States, the BackSID is a little easier to get because they are closer to home. Do you have any experience with it? I read that it doesn’t allow Audio Pass-Through and I am not sure what that means in context of the TherapSID. I guess that means I can’t run audio in and use the filters, but that is an experiment that would be down the road anyhow.
I discovered today that the ECC-5 original carrying sleeve for the Models (not the currently available ECC-5b) fits the Therapsid MKIII very nicely.

Brilliant, looks like Blastbeats got an update as well.
Nice! I have two on the way now! I’m in for quite an update session
I just updated and can confirm that the Filter Mode button now toggles between add’l combination filter modes. Looks like they’ve also been added to MIDI CC 55.
