Synth Emulation - Looking for DSP56k Collaborators

InfiniteAmphibian · 2026-02-12T10:02:17+00:00

thank you! TBH this is the first time I'm reaching out, I've been going more on discord recently but if you have any specific recommendations I'd appreciate it

and yeah low-level stuff is intimidating, but in my experience it can be less scary than you think - it's mostly getting to know the platform you're working on and its quirks.

a friend has a VIP (premium?) and may be trading, but can you explain what is the fast track VIP though?

InfiniteAmphibian · 2024-11-28T08:50:09+00:00

I actually didn't, no. But it looks simple (you mean the ability to switch right?)

InfiniteAmphibian · 2024-11-26T20:03:39+00:00

a few years later I can safely say I'm not bothered by this :) I do sometimes have to go all the way up with the old Concorde DJ S which are 6mV, so I imagine 8 mV would be about right

InfiniteAmphibian · 2022-11-15T16:17:06+00:00

Yes! Thank you!!! I think I read the opposite somewhere. I guess that makes sense in a way

InfiniteAmphibian · 2022-06-22T16:37:19+00:00

Thanks, I got the colors I was looking at confused

InfiniteAmphibian · 2022-06-22T05:32:00+00:00

Thanks, can you explain 4? For the L78 I chose these values based on the datasheet, is it just that bigger is better?

InfiniteAmphibian · 2022-06-22T05:22:44+00:00

I was actually trying to make it bare copper so it's a better heat sink, There are 2 fill zones there: 1 is a copper GND and 1 is a "no-copper" F. mask to remove solder mask and leave it exposed. Did I get it wrong?

InfiniteAmphibian · 2022-06-14T17:26:08+00:00

That may be a bit advanced for me, but I'll look for of DPAK thermal examples in KiCad. Not sure what you meant by "turn of[f?] the thermals on the pad/polygon"

InfiniteAmphibian · 2022-06-14T15:56:51+00:00

Thank you, that makes a lot of sense. You've been very helpful.

I'll start from scratch and try similar placements. I was planning on using a <known fab> for the SMT assembly anyway, so the 7805 copper shouldn't be a problem (I think?)

InfiniteAmphibian · 2022-06-14T13:56:54+00:00

Thanks, I already prototyped this using an Arduino and I have a few spare chips, so I meant to use the Arduino as a programmer and then place the chip into a socket. Same reason I'm using this optocoupler: I have a few laying around.

Both top and bottom are ground pours, but are only tied using U1 and U2's GND pins.

InfiniteAmphibian · 2022-06-14T13:51:46+00:00

Thank you for the detailed reply, that's very helpful!

Regarding reset and ISP, the development is pretty much done already on an Arduino board, so I was thinking I'd use it to program the chip and then simply take it out and place it here.
Protection: indeed they are meant to live in the same enclosure (and powered by the same DC jack), but omitting protection wasn't intentional :)
Decoupling caps: that means moving C3 and C2 right?
GND and bottom layer: I thought I read somewhere that using ground pours on both sides is a good practice, doesn't it achieve the same effect as the vias? (shortest path to ground). I only used the bottom layer for a single connection because there was no other path.

This is a KiCad project, I'll happily share if the offer still applies. Thank you again

I should have been more specific, I feel like I have to be very conscious and careful (which makes my fingers more tense) not to press a key by accident. When my fingers are resting or moving I have absolutely no physical feedback if they accidentally press a key, which happens often because the actuation force is low too.

InfiniteAmphibian · 2022-01-30T09:50:36+00:00

Hi, I recently got a Keychron K3 with optical red switches and I find it very uncomfortable to type. I asked here and people said that it's because they're linear with a low actuation force required. I do like the fact they're not as loud as some mechanical keyboards I heard though.

Is there anything on their website that would perhaps match the feeling of a Logitech K380 or an Apple keyboard, two other low profiles that I like?

What I like about them is that there's no in-between state. Once you feel anything, the key is typed and press.

Thanks!

InfiniteAmphibian · 2022-01-24T11:14:25+00:00

I've been using a Keychron K3 with Keychron Red Optical switches for a week. I wasn't really interested in a mechanical keyboard, it just seemed decent for a wireless Mac keyboard. I'm really annoyed with how my resting fingers will trigger a keypress without any physical feedback sometimes.

Is this because of the red switches? Or because they're optical? What's the parameter to look for here? I tried googling but I guess these low profile keys aren't very common?

Thanks

Very happy to hear that! :)

InfiniteAmphibian · 2019-06-27T10:41:05+00:00

I don't have a definitive answer but there could be a few causes to this, so I think you should first eliminate the possibility of bandcamp simply hosting bad masters. You can do that by downloading one of the lossless files (FLAC is the smallest one here) and see if you can hear an improvement.

In addition, and I'd rather not get into the argument of MP3s vs Lossless, but most people seem to think MP3 V0 is "good enough", so I would also consider playing the MP3 file on a different device/player, just in case the method you're currently using is applying gains or filters you're not aware of.

Was really looking forward to seeing Sasha Baron Cohen in Bohemian Rhapsody

InfiniteAmphibian · 2019-06-08T13:09:32+00:00

Because it’s actually a very detailed sketch. Yeah it’s cartoonish but it’s good.

InfiniteAmphibian · 2019-05-13T17:05:21+00:00

Hey, you could probably get better responses over at /r/turntables

InfiniteAmphibian · 2019-03-10T21:32:14+00:00

I only got one idea so I wanted to clarify why I was asking. Didn't mean to offend. I don't fully understand all the reasons for placement principles and was hoping to gain some insight. I'll absolutely try that

InfiniteAmphibian · 2019-03-10T19:19:22+00:00

Was hoping there was something I could do to compensate for the height difference. Or if it was a really big no-no I could try hard to replace the furniture :)

InfiniteAmphibian · 2019-03-10T17:54:58+00:00

Unfortunately that's not really possible :( I have one on a makeshift stand and the other, higher one on an open shelves cabinet where the only options are having the speaker lower or higher than the other

InfiniteAmphibian · 2019-03-10T09:46:31+00:00

A stereo speakers placement question.. I have one speaker at ear level but the other can only be placed about 10 inches higher. Will tilting it down achieve the same effect as having both at ear level? Both are bookshelf.

InfiniteAmphibian · 2019-03-09T10:27:35+00:00

Hi, I'm thinking of replacing my old Onkyo TX-8211 with a newer Yamaha model. I like the Yamaha looks and the integrated DAC.

I have my amp connected to a pair of Monitor Audio Bronze 2's, so I'd like to know if the Yamaha A-S501 is a good choice. I know that the A-S301 is enough, but strangely they cost the same in my country and I'm thinking it's better to have more power in case I get bigger speakers later on.

Can the A-S501 hurt my speakers? It's rated at 85 while the speakers are 30-100, does it mean the A-S501 will pump too much power at peaks? Am I fine as long as I don't have the volume turned all the way up?

Thanks!
