Modular vid #331

video upload by Phisynth

"Here’s the Max/MSP interface I’ve built to control the awesome Destiny+ Model Q-2. The amount and variety of sounds you can get out of this little device is totally insane. All sounds are coming from the MQ2, with a little delay/reverb from the Eventide Eclipse. The patch is almost done — I still need to build a proper preset management system…

Sequential Showdown: The Surprising Winner...

video upload by Rapid Flow

"In this video, I'm doing a comparison between the Sequential Prophet-6, Prophet-600, and Prophet 10 And the results might surprise you... We're breaking down the raw oscillator tone, the drift and vibe, filter character, best use cases, and that elusive 'vintage soul' to help you figure out which Sequential legend truly belongs in your studio.

If you want exactly these 3 synths in your DAW, get Zensphere! (I sampled them note-by-note). https://www.rapidflow.shop/products/z..."

Comparing the Sequential Fourm to the Pro-One

"I Compared the Sequential Fourm to My Pro-One" video upload by Starsky Carr

0:00 intro jam and info
5:04 Really Deep Bass - THE FILTER
9:14 They've got Oscillators
11:24 Creating a Few Tones
15:11 PWM and how to match them
19:10 F to the M
20:00 Show Me The Sync
21:19 Pushing the Envelope 24:06 Overall..?

"Some genuine surprises in this head-to-head with the Sequential Fourm and the legendary Sequential Pro-One to find out if the Fourm can give the same vibe.

At first glance, the architecture looks familiar: dual oscillators, classic envelopes, a focused modulation section, and unmistakable Prophet-era DNA from Prophet-5 territory. But the big question is this: does the Fourm capture the raw punch, deep bass, and aggressive character that made the Pro-One a cult classic?

.. and I know it's not a clone :) but in this in-depth demo and comparison, I explore:

Oscillator behaviour, sync, PWM and FM
Filter differences (including low-end depth and resonance extremes)
Envelope response and modulation range
Bass performance, subs, and room-shaking tones
Where the Fourm goes beyond the Pro-One — and where it doesn’t

Rather than obsessing over perfect null tests, this video focuses on feel, playability, and whether the Four inspires the same kinds of sounds and musical ideas as the original Pro-One.

If you’re into analog monosynths, Sequential gear, vintage vs modern comparisons, or you’re wondering whether a contemporary synth can truly stand in for a rising-price classic, this one’s for you.

🎧 Headphones or proper speakers strongly recommended — some of these bass tones go very deep."
