To celebrate international joke day 2023, we decided to take a big step with our first synthesizer plugin; SUBscription. While based on a tongue-in-cheek pun about the current state and direction of the music tech industry, we actually ended up with a surprisingly excellent plugin that takes user-generated phrases (subscription codes) and converts them into unique waveshapes in a monophonic sub-synth. - Create powerful, characterful bass sounds - Unique and exceptionally high IQ text synthesis technique ^TM - Reasonable subscription models - Unequivocally superior, requires no review. SUBscription Upon entering a subscription code into our brand new text-to-synthesis engine, you are entering a world of sonic enrichment and fame, but you may have to make a deal with the devil. Text Synthesis Create characterful wave shapes using our experimental new text-to-synthesis technique. We have prepared every possible character combination (subscription code) because you’re weak and predictable. Drive & Dirt Boost the ever loving **** out of the synth with some crispy drive. Use the Dirt knob’s Rate modulation to thicken and filth up your tracks with noisy textures. Filter Carve your frequencies out with the 12dB/oct low-pass ladder filter. Much like the filter, we too will be filtering out any bug reports, requests or errors - our time is far more important. Modulation Add movement to your sounds with 2 envelopes, 2 LFO’s & 4 expression controls which are assignable to nearly every parameter. Unlike the fluid nature of modulation, we stand firm with our decisions - you just wouldn’t get it. Product Aftercare If you need support via email you’ll have to deal with harshly worded, incredibly frustrated developers and please note that all critical feedback of any nature will be met with serious scolding. SUBscription is designed as an AUv3 plugin, meaning it works within iOS and iPadOS hosts such as Logic Pro, GarageBand, Cubasis 3, AUM and Beatmaker 3. SUBscription also works as a standalone instrument.
