Thanks for the great suggestions. When I get a chance I'll try them out.

It's a frustrating issue that is for sure. I only have the Tsunami on the isolated voltage regulator / converter. The unit that I bought was a Powertech brand and it was the 9 to 36v input and 5v output with a current rating of 600mA. The specific model is the PD4W30S2405D-MAD. Not a cheap unit at a...

Not in the expect way where you have a root key for the sample and the sample is played back at a different speed to change the pitch. You would have to create a separate sample for each key that has been pitch shifted. Not that complicated really.

Does the Wav Trigger work without the arcade controller by just shorting out the trigger connections ?

I don't know what an arcade controller is or how it is connecting to the Wave Trigger ?

Thanks for the tips DSp. The best solution turned out to be the dc to dc isolator. Not a hint of noise out of it now. Clean as !

For reference this is the unit I purchased - http://www.putpowertech.com/products1_1.asp?index_no=92

Just wondering if you've thought about a "low tech" solution like markings on the drivers side wall or on the floor for visual lineup. Less likely to fail as well :-)

There's not enough hours in a year ! I've been working on this for two years now and it does weigh me down quite a bit. I'm going back to doing music part time as of March so things will slow down a little more but I am hoping to get all the hardware into the box and maybe even wired up as well. I'v...

That's the giveaway that it's not ground loops I think because the noise never changes. In fact it will multiply as you use more of the outputs from the Tsunami. No the VCAs were totally open the whole time. Still to try out the DC to DC isolator which I might do today or tomorrow.

It's an odd one. I think I have a solution which is an isolated DC to DC converter module. I've not tried it as yet. It is certainly related to grounding I think. The odd thing though is that the noise disappears a few seconds after all samples have finished playing. I would have thought your "stand...

I'm building a sample player synth which uses the Tsunami as a sound source with the four stereo outputs being fed through stereo VCAs so I can control them individually. Lots of analogue stuff on the output which is all stereo with stereo LFOs. I've written some LFO code which in turn sends pitch b...

I hadn't run into the problem but I was also just numbering my files.

I'm using a Mega2560 Pro Mini - https://robotdyn.com/mega-2560-pro-mini-atmega2560-16au.html mainly because I needed multiple hardware serial ports which you may also need especially if you plan on using external MIDI control as well the Tsunami. You'll need hardware serial connections for that. Of ...

Alas I don't think there's any way to get information off the wav Triggers sd card. I'm working on a project where I also need to know details of the sd card's contents. I've attached a sd card reader to my Arduino so I can store details of the wave Triggers sd card which I need to access for perfor...

If you're using the Roger Clark based arduino core https://github.com/rogerclarkmelbourne/Arduino_STM32 then make sure it's up to date. I recently had some multiple processor issues with I2C which fixed this. My issue caused the STM32's to freeze up. Also if you're using the onReceive function, I do...
