![]() First thing to say, Supermassive comes up under ‘Reverb’ in Pro Tools, but hey you can make reverb with a delay. Three knobs, one unobtrusive switch to more than double the delay time (300ms to 800ms), beautiful thick repeats, easy to dial in for rhythms even without tap tempo, and able to to do. I’m gonna break down each of these top FREE delay plugins below. Trial & error benchmarking with a scope is probably a more sensible idea than attempting theoretical calculations. Digital DD-3 Analog DM-2W Throwing in another vote for the DM-2W, if it’s analog you’re looking for. The MXR Carbon Copy is one of the most popular analog delay pedals here at Sweetwater. My whole point here is that accurately calculating how much time this code will actually take is difficult. Since the compiler decided to involve the stack, data caching could also play a part. Best delay pedals 2023: classic analog and modern digital delays to give your tone new life. Pipelining, branch prediction etc will mean that the code might execute faster than just the sum of the clock cycles though. For example ARM gcc -O3 -ffreestanding gives: dirty_delay:įrom there on you can in theory calculate how many ticks each instruction takes and change the magic number 50000 accordingly. The classic delay pedal Specifications Type: Digital delay Bypass: Buffered Tap- tempo: Yes Modes/patches: 4 Today's Best Deals Check. This is guaranteed to generate various crap code. Best delay pedals 2023: classic analog and modern digital delays to give your tone new life. For example: void dirty_delay (void)įor(volatile uint32_t i=0 i<50000u i++) If you want insist on generating a dirty busy-loop, then it is sufficient to just volatile qualify the loop iterator. Many architectures (like Cortex M, iirc) are free to skip NOP on the CPU level and actually not execute them. Using NOP instructions might not work.Toggling a GPIO pin repeatedly is a bad idea since this will draw current needlessly, and potentially also cause EMC issues if the pin is connected to traces. ![]() ![]() Optionally, you can even let the CPU sleep and use a wake-up interrupt.ĭirty "busy-delay" loops on the other hand, are rarely accurate and come with various problems such as "tight coupling" to a specific CPU instruction set and clock. These have the advantage that the timing is precise, deterministic and can be easily adapted if CPU clock speed is changed.
