Vlychada Beach Peloponnesos, Greece
zhlédnutí 184Před 10 měsíci
This year (2023 april/may) we went to Greece with our camper which is a Hymer B524. Driving down (and up again) to Vlychada Beach was the most scary ride this year... But very much worthwhile. The see is fresh, clear and full of fish. And...... NO reception with the phone AT ALL...

Hi zijn dat nou eurorack modules of 500 serie? interessant
Dit zijn zelfbouw euro rack modules waar ik de S2 Waveblaster en de EWave waveblaster gebruikt heb. Gekocht bij Serdashop.com De frontjes heb ik met een 3d printer gemaakt.

Man, you did a great job, that sounds really great.
Thank you!
does this run on a real opl3 or is it just emulation ?
This runs on an YMF262 chip.
How do you setup the launchpad to the Raspberypi?
I just plugged it in one of the usb sockets and it works...
Very Nice!!!
Hi, I think this sounds very interesting. I have a MN3102/MN3207 pair lying around I would like to attempt to build something like this, would you by any chance be willing to share the schematic for this module?
electro-music.com/forum/viewtopic.php?t=73350 If you have any questions dm me at electro-music.com
@@DutchBigEd Thank you so much, very much appreciated!
To be honest I would prefer the opl3 sound chips then the built-in Microsoft wave table synth but I do come back to it every now and then to hear those cheesey gm synth that was embedded with Microsoft windows computers.
You seemed to have made the Euro rack out of this, how is your volume control setup in this circuit?
@mm-qk3eu I made a single dx7 instance Euro-rack module with a Raspberry PI Zero and you can change the volume by midi commands and by using the rotary encoder.
erg mooi, spannend weggetje....
The world has such beautiful places but it is very brave to drive there with a caravan. I wish you a nice time.🎉

@@DutchBigEd I've been thinking for a long time how to get three miniDexed in one housing and when I saw different housing colors it was only a small step: search for pictures on google: "zeitmaschinen Display"
I’m having a hard time getting mine to work with midi do you have the code available?
There is no code involved, just add the suggested midi input circuitry and add this to the wavtrigr.ini which is on your usd card: #LPWR 300 #MIDI 1 that's all there is to it!
Thank you ! I will try it out!
What an interesting chip. Could you share the schematics? Where didyou get it from? Cannot find it at conrad, Reichelt or Segor...
I got them years ago as samples. www.modwiggler.com/forum/viewtopic.php?t=248810#p3725357 here is the first iteration of this project, a dual switched capacitor filter.

Dude you are making all these badass modules, serious gear envy. Nice work! Got any documentation for those of us who are completely lacking in creativity?
www.synthforum.nl/threads/3807078/#post-3879423
This is so cool, I've dreamed of building something similar. Do you have documentation?
I’m happy to help and share whatever I have, but it will take some weeks before I can acces my stuff.
Very impressive work.
Thank you
Very cool and impressive! Nice work. I have dreamed of doing something like you did here. Connecting these cool old school PSG chips thru midi. Did you document any of this? Are your schematics and source code available? Thanks!
electro-music.com/forum/viewtopic.php?highlight=ymf262&t=68149
I'm not sure this is the final version, but I can't check it at this moment.
Does this do FM synthesis like the YMF278B? I've heard both chips are called OPL4, but this one seems to be stripped down.
This is an eurorack module I've built. The YMF704 can do both FM and Wavetable, in this module I use Wavetables only. The YMF262 used on this channel does FM.
I wanted to trigger the DSP D8 using another arduino but the DSP D8 triggers on low. Did you alter the code to have it trigger on high?
Yes, I do remember I’ve altered the software. But at the moment and the next 5 weeks I can’t access my software. If you have the patience just pm me again in 5 weeks and I’ll help you out!
I want this too. The chip looks amazing, please share more info :)
More on this please

Okay now I feel pretty silly, cuz I haven't actually sat down at my desktop and tried to genuinely understand this, but apparently the first time I read your description of the circuit I missed the fact that the first few chip functions were not signal processing but controlling an EEPROM. I don't have a very thorough understanding of the function or usual application of that particular analog devices chip. After the reading the first three paragraphs of the data sheet, I'm even more unclear. Regardless of how it's done, it's incredibly impressive that you have homebrewed this and it also sounds very very beautiful
This is a reason why smartphones are dangerous, LOL it allows you to read things you maybe shouldn't first thing after you wake up
That's a pretty bonkers way to do wave table synthesis
I received your comment as a compliment since you subscribed to my channel, but was it a compliment?

Blue pill? Will you share the project on github? Very interested!
I'm sorry, not a github user but soon I will write more about this module.
Exactly the module and hp size im looking for! Is this noob diy friendly?
This is a one-time design and build. I designed the face plate with Fusion 360 and printed it on my 3D printer and the circuit is soldered on perf board, so no, although this is not the most difficult build, this is not considered noob friendly...

Hi Im looking at using the AD5761 to make a smart function generator using ESp32 looking at your SPI code for Blue pill as partial gude. You use a table and push the data out to the DAC. Q1 what is your highest freqency? (I need to make 20Khz wave forms with about 32 samples in them). I can send SPI out via DMA to get my arbitrary wave forms from memory at high speed. Q2 You set the opamp to 2.5V ref. was this to set a DC offset? I would like to control offset via the micro. (Not be pushing the data , but setting it in the hardware) kind regards Dave
Q1 in this setup I measured the following: min. time between samples: 9.4 uSec (0.106MHz) so 20kHz is totally possible. max. time between samples: 64.1 uSec (15.6 kHz) time CS is low: 8uSec (this is the actual load time of the DAC time between trigger going high and first CS going low: 17.8uSec (using TRIGGER 2, being the slowest of two) Q2: the 2.5 volt Vref is there to set the output voltage of the DAC and is used in the amplifier following the DAC to remove the DC offset generated by the DAC. This is actually a fluke, since if you read the datasheet, it shows that the DAC can be configuered as bipolar, that would have been easier and more straight forward.
After writing the last answer, I changed the program to have the DAC put out a bipolar voltage (±5 volt) and removed the Vref from the first amplifier.
@@DutchBigEd many thanks for the detailed timings. Hopefully I can use the DMA to get high speed memory transfers to the DAC. I need to make a function generator that will make arbitrary wave forms with a 20khz timebase. The DAC you used is ideal as you can program it to be bipolar so I can even do the dc offset in code. Regards Dave
Still nice. Did you release schematics and source somewhere?
electro-music.com/forum/viewtopic.php?t=66798 this is all there is online about it, I'd do it differently if I would design a New one...
Very interesting. I see progress and the implementation of your ideas. I'm waiting for a description and software. Gardin is a sin.
Ok. How?😉
@Roman Opekushin I guess you are referring to the midi splitter, I’m still in the process of working on the software. But what I do is I designate a channel to the three midi outputs in the software, so if the midi file playing on the computer plays a note on channel 0 (e.g. 0x90 0x32 0x80) this note on goes to the connector designated as channel 0, if the note-on is: 0x91 0x32 0x80 the note goes to the connector set as channel 1. I also added a Patch command in the YMF262 players, so I can change the instruments with a midi command.
@@DutchBigEd Thanks for your work. I'm waiting for the midi splitter device. And his software.
good job !
Thx 🖖😁
It's fine. How do you divide MIDI by synthesizer? You have a device for this. Give a diagram and description of this device. It makes no sense without it ...
It is still a project in developement, one big piece is missing: i plan to involve a sequencer in this module
Cool cover! I subbed to stay connected :)
