...when I noticed something weird in the supplied gutshots ....

USB port? It's probably a microcontroller programming interface.

I'm actually not quite sure what we're looking for..

are you talking about the unconnected wire, the general ratsnest or the USB?

Ha ha I've been staring at that pic wondering what's wrong with it too...

The wire indeed.
I guess with certain effects one wire less or one more is not going to be that noticeable :-)

I would assume that's one or maybe two wires not used from a ribbon cable.

You're right, I had not thought about that ..
Darn, now I am again tempted to bid ...

I nearly posted on Droogies Id Tap That build report that he should post to some gear forums "Count to ten proto reveal".

Ive not heard any demos of the CT5, is it worth the hype surrounding it?

I think it's the best pedal ever created, seriously. I needed a month to learn how to use it, and he is adding more functionality every month or two, I regularly download the firmware and put it in to try em out.



Here's a video my friend recorded for it, I was playing here (rather bad but f it) , I even made a controller for the CT5 so I don't have to use my hands nor an exp pedal while playing it. It is a cheap pedal for what it offers, it can do everything you can imagine.
The sounds around 04:50 alone would've justified the purchase for me. It is so much more interesting than the EHX Freeze (that I also have lol)

Heh I was actually watching that demo earlier :-) Have you ever had a peak inside to see what kind of DSP chip it uses?

I wasn't interested to be honest, he does say somewhere on his videos that it is some sort of ... ah, I found it

"ct5 is built around a 32-bit arm based mcu from st (stm32f4 series). i never used the fv-1, it looks fun, but from the specs it is pretty weak compared to stm32 or any other high powered mcu on the market right now."

Thanks,
These chips sure offer a lot more horse power but I really don't have the skills to program that.
Well for now I guess I'll keep fiddling with my puny FV-1 then  ... ;-)

100% agree, I use mine all the time. Haven't even updated it yet (which I should).
Mind sharing some info on the controller you built for it?  8)

oh it's nothing much really - https://www.instagram.com/p/BGtLIylqPPH/ (I just can't find a better picture)

it's a TH Custom Pro-cessor with one of the sends foot-mutable so I am actually giving CT5 the ability to have delay tails, and the other two footswitches are just going between a couple of exp settings so I can go from standard delay to reverse to up a fifth (for example) all with the footswitches while playing. It really makes it killer to use with a band.

Tried it for an afternoon - it's a really nice pedal, definitely not a one trick pony.

I agree with the Instagram comments that this deserves a demo :)

haha there is one actually recorded but it never did see the light of day!
I will have to urge my friend to produce it soon, the audio and video is in his folder somewhere... I just have to send him some good pics of the controller itself

They're probably using a Cortex-M4F with the floating point processor, ST makes several (like the STM32F446--the Nucleo STM32F446 dev board is $11 from Mouser). ARM/Keil provides pre-compiled floating point DSP binaries which do a pretty good job. To use them you will have to program in C on the platform, not mbed or some other. The biggest drawback about ST is they don't have an end-to-end toolchain and using the free, not size-restricted, tools like Eclipse + GCC along with ST HAL program is a pain.

I played around with ST boards a few months ago, and after wasting a lot of time with their toolchain I'm using Cypress PSoC, TI TivaWare, and Teensy instead.

The built-in ADC/DAC on the STM32F4 are pretty crap 12-bit jobs so I'm curious what he's using for that. The FV1 is using 24bit ADC/DAC (albeit limited to 15k BW) .

cant comment on the specs of the device but what I know is the CT5 has the best tone of all delays I have ever tried, it is just so present in a band mix and it keeps my guitar tone uncompromissed at all times, it's regular delay is even more pristine than the Boss units

This is the part that I'm most interested in! Any chance you'd be willing to share some details on how you made this happen?  ;)
Thanks!

yeah sure it's really easy, imagine your potentiometer from your expression pedal being in a standard pedal enclosure, and in that enclosure you have two more pots. on the side of the enclosure you put an exp jack and then you connect from there to your CT5 with a stereo cable.
now all that we need to do is choose which of the 3 pots is connected to the exp jack and going into your CT5 or some other pedal. that is being done by the footswitches, they just assign the jack to any of the pots. So I have 3 exp settings to alternate between with my foot.

Nice! That's what I thought you did, but just wanted to verify. May have to build one to go along with my CT5 =)
Thanks!
