I’m not an engineer by any stretch of the imagination - I’m a guitar player who has soldered a few analog pedals and opened an old modeller once to see if I could fix the power jack that had come loose. So I greatly admire your expertise and patience when disassembling and reassembling this unit. Also, it’s very cool to get an independent assessment of the quality and cost of the unit. I was hooked from the beginning to the end! =)

Fascinating breakdown. The engineering looks very good, except for the passive heat dissipation. I've got an HX Stomp. I keep a computer fan running next to its upper left corner, to wick away the heat, as that's where the screen is and where it gets the hottest. Works surprisingly well. Heat is the enemy of electronics, but there are simple solutions. Thanks

Hi, Wilson! Thank you - I really enjoyed this video. I also want to say that the Paint Audio MIDI Captain is a *perfect* complement to the Quad Cortex, and an incredible value. Anyone who owns a QC and appreciates its hands-on UI as a desktop unit should also own a MIDI Captain for 1-to-1 mapping of switches on the floor. Paint Audio caught me completely off guard and I've been consistently impressed with your products. Best of luck going forward!

I disagree about the screen being the cause of how warm the unit becomes. If you put the unit into standby mode it still kicks out the same amount of heat. The case does a great job of being a heatsink though. Great to see it's well engineered and well built. Also, really nice that its built in Finland rather than the far east.

After around 10 year of use my Kemper powerhead LCD has darkened that reading the letters was barely readable even if there was backlight. then the silicon buttons are already yellowish. About a month ago I heard a a thud and then its gone. Apparently the power supply gave up. I called Kemper helpdesk and still having difficulty sending it for repair until now. My only regret is that I haven't used this for more than 50 times because I'm a busy person. On the other side my Axe Fx is still running flawlessly. I think Quad Cortex is build a lot better than Kemper .

@pdiddysea8599 7 ай бұрын
@@SebastianBogensperger i dont really agree though I see your rationale mainly because they used such an out of date format. I am pretty sure most people would not have that cable format handy anymore especially if you need a long one as I did. USB is the standard and is being enforced in Europe across a lot of devices for uniformity so I suspect as the laws start getting enforced you will see a USB-C QC come out. I had to buy a special cable that terminated in USB-c so I could plug it into my mac. A cost I should not have to pay. But it is a trivial complaint over all. I was more pissed when they dropped the price bc I felt like I got taken advantage of. At least offer us some plug ins etc.

I have been thinking that the sharc dsp days are numbered. The ARM V9 stuff runs at a much higher clock and has a higher core count. For $10 you can get a 800MHz dual core A9 chip, or a quad core arm for not that much more. Unfortunately I have seen ARM based designs use embedded linux (fender mustang gt), this ends up causing 4mS of latency (measured using the free software on my channel). This pedal could have much better latency, but it depends a lot on the software design.
@Wilson-PaintAudio Жыл бұрын
Yes, I think currently SHARC DSP still has its advantages in audio processing, and there are historical reasons as well, such as commonly used algorithm libraries. While other application-level processors may have higher clock frequencies, they may have shortcomings in terms of latency, vector processing, and parallel multiplication and addition operations. We can think it is like a GPU and a CPU. However, technologies like NEON (Advanced SIMD) in ARM have already blurred the boundaries between audio DSP and ARM.
@moddaudio Жыл бұрын
@@Wilson-PaintAudio I looked at analog devices offerings nowadays, Its been a couple of decades since I used one (Gibson MaGIC), they have chips with dual SHARC cores plus an Arm A9 and some some coprocessors for FFTs and IRs. Clock for clock the SHARC would absolutely beat an Arm A9 for this workload. But, thanks to cell phones, the Arm chips are more mature with higher core counts and clock rates. Plus the tools are free on arm rather than the 1K + yearly subscription fee for the adi chip. I guess I was confused by the product name, as an engineer 'quad cortex' to me implies Arm, I was surprised it was SHARC based.

Disappointed with the encoders as footswitches. I thought it would be something more sturdy. The plastic shaft is sus. I know, the upper part takes the hit and the distances are set to not force the encoders. But anyway... And about the cost, the more important, the software.
@Wilson-PaintAudio Жыл бұрын
Understand your feeling. Me too! However, I don't want us to mistakenly think that this plastic thing will be fragile. In fact, it is capable of fulfilling its functions, and from a design and manufacturing perspective, injection molding is also the best choice. What I think it can be better is that the foot button actually feel a bit stiff when stepped on, expecially when a little deviating from the axial direction.
