Paperoga build - 11/21/2022

video upload by SynthMania

"The slow build of 'Paperoga', my newer portable DotCom, ancillary to Brigitta (but also great standalone). Paperoga (Fethry Duck) was one of my favorite characters of 'Topolino' (Mickey Mouse), a popular Italian cartoon magazine from when I was a kid in the '70s. Here in this video we are testing some oscillators, filter, envelopes. Drums from Cubase DAW."

Note the sequencer is a SYNTHETIC SOUND LABS - MINI SEQUENCER II. Some info via Noisebug:

"An upgraded version of our popular 1651 with greatly improved features. A collaboration with our friends at Division-6.

Feature enhancements over the 1650 include:

7 sequence memories
5 song memories (string sequences together)
SLUR- change pitch between steps without firing gate
Variable gate timing (including ratcheting)
ACC can be set to drop or not drop between steps, or follow gate timing for that step
Auto-advance step when programming
Live transpose (use the keyboard to shift entire sequence up or down while running)
Live edit (buttons you push while running get saved to the sequence)
1X mode (disable to use XP IN as a reset without requiring an external gate mixer)
Clock out (use ACC out jack to output clock if using internal clock)
The 1651 gives you standard CV and pulse out, plus an ACC out (Accent? Accessory?) Use the ACC output to open up a filter, enable a glide, trigger a drum, or whatever you can think of.

It has its own internal clock to get you up and running in a hurry, but you can connect an external clock if you need greater control of tempo or want to sync with other devices.

The module can store up to 5 songs of 16 sequences each, and 7 sequences of up to 16 steps each. Wow!"

DIY DRUM AND BASS SYNTHESIZER ESP32

"Sebelumnya saya sudah berbagi skema dan program data tetapi hasil keluaran suara stereo masih terlalu banyak kebisingan dari tampilan oled dan catu daya, sekarang saya mengubahnya ke tampilan Hi-fi dengan keluaran mono itu terdengar lebih baik. Jika kalian ingin membuatnya saya sudah menyiapkan data dan skema baru di google drive saya .
Link data dan skema :
https://drive.google.com/file/d/1-f2K...
.
Modul ini di buat dengan micro controller ESP32 dengan keluaran suara PWM mode Hi-fi tanpa penguat operasional saya rasa sudah cukup
.
Gunakan catu daya 5V / 1Amper di pin Vin jika inging menggunakan adaptor jika port micro usb cukup charger smartphone saja"

Googlish:

"Earlier I shared the schematic and data program but the stereo sound output is still too much noise from the OLED display and the power supply, now I changed it to a Hi-fi display with mono output it sounds better. If you want to make it I have prepared the data and new schematic in my google drive .
Data link and schematic :
https://drive.google.com/file/d/1-f2K... .
This module is made with an ESP32 micro controller with a Hi-fi mode PWM sound output without an operational amplifier, I think it's enough
.
Use a 5V / 1Amper power supply on the Vin pin if you want to use an adapter, if the micro USB port is enough for a smartphone charger.

SEM by NYZ

"Originally released November 21, 2022 available as limited physical edition CDr & name your price abridged digital on Psøma Psi Phi =>

pspsph.bandcamp.com/album/sem

SEM is a long form drone made using a single instance of the GForce SEM - a faithful recreation of the 1974 Oberheim monophonic analog synthesizer, reinstated on the occasion of Tom Oberheim's birthday. Not completely familiar with the machine prior to this session, but previously having played with other Oberheim designs such as the Matrix 6R and XPander, Burraston opted to simply explore it without any additional machines or effects processors, in order to allow the SEM to illustrate its personality naturally, which resulted in the gorgeous pillar of tone that sits before you now. Thematically, SEM relates to prior NYZ recordings such as OSC2 at Superpang and the independently released BS2::DRN4, although avid listeners will appreciate the uniqueness of SEM even when aligned with earlier work. SEM was made possible with the generous assistance of Jerome Meunier at GForce & AFX, and is offered as the twenty-first recording issued in the NYZ subcatalog at Psoma, continuing a rich lineage of vivid synthesizer music and unmapped experimentation."

"This is probably the rarest and strangest bird I've met. You may think it's a kind of simple monophonic analog 1 oscillator synth like the Roland SH 2000, but there is more than meets the eye. It took me some time to understand what's going on and to this day I am still not sure exactly how it works but it looks like the oscillator is a kind of very early FM based oscillator. Check the video, especially the "bell" presets and you'll know what I mean.

Tone is shaped by 3 faders labelled "Fundamental", "Overtone" and "Brillance", and these are interconnected.
There is a simple envelope which works as attack decay (labelled "attack" and "sustain") by default but can be switched to attack release by the push of a button ("sustain long"). Funny thing is the attack fader is inverted compared to classic synth topology: when raising the fader the attack gets shorter.
All the presets have their own envelope setting and depending on the presets the attack and decay faders do not behave exactly the same, ie the envelope faders do not totally overide the presets envelope.
You can also have the envelope assigned to the filter by switching on "VCF expand", and control the envelope to VCF amount with the "Expand" fader.
The "Expand Envelope" seems to invert the VCF envelope. It's quite efficient on some presets and not on others.
"Touch portamento" switch is actually a key retrigger option. When activated envelope retriggers on every key stroke (low note priority) otherwise the envelope is legato. So it has nothing to do with the "portamento" fader which is indeed a portamento effect. "Gride" is basically a pitch bend (upwards only).
"Growl" switch adds... growl: it adds a kind of brassy attack to the sound. Not efficient on every preset but can add to the realism of the sound on others.
There is also a LFO which can be delayed (it's more like a slow attack then a proper delay), consisting of either pulse or triangle wave shape, that can be assign to "vibrato", "wow", "chorus", "tremolo", and you can have the envelope repeat on the lfo speed thanx to the "repeat" switch.
And finally there is a noise generator with dedicated fader level and a "Noise only" switch that is self-explanatory.
This makes for a uncommon and interesting monophonic synthesizer. Very expressive in my opinion, once you managed to tame it.

I did service this one as much as I could but without any information and service manual it's hard to be sure it's sounding as it should. There are like 15 trimpots inside to calibrate the synth and you definitely can hear most are changing tone and harmonics.
Anyway it seems to fully function, it's scaled and tuned and it sounds great but again I can not be 100% sure it's sounding as it was intended.

Cosmetic wise the synth is in good condition, especially considering the rather cheap build quality. But of course it has some scuffs here and there."

"All analog japanese drum machine from the 70s. Classic sounds and patterns from this era. Very nice sounds and inspiring patterns (20 in total). There is a balance knob that can fully mute the hi hat and cymbal, very handy for more variations. Also a sustain knob controls decays of the instruments except for cymbals and offers a wider range of sound (from a deeper kick to a very tight one for instance). All in all a very charming box. It has been serviced and is fully working. Like on all those boxes there is a slight hum in the background due to the power transformer but it is not a problem neither on stage nor in the studio."
