I work as a fractional product marketer and growth operator for subscription software companies, partnering directly with founders to clarify product positioning, improve conversion across the customer lifecycle, and make revenue performance legible.

Earlier in my career, I led product marketing at a B2B scheduling SaaS where I facilitated a 20% increase in trial-to-paid conversion and ~$700K in incremental ARR over three years. 

Today, I work with a small number of companies at a time, embedding closely with product and engineering to improve clarity, conversion, and retention, especially in situations where growth has plateaued or metrics are difficult to trust.

Former clients include Suno, WAVS, Kits.AI, Neural Frames, Lemonaide, Sesh.fm, NeuTune, Water & Music, ACE Studio, Audio Design Desk, RipX, HookTheory, Samplab, and others.

Dreamtonics just launched a powerful, ethically-trained AI Choir tool for composers and music producers. 🚀

The new AI choir feature expands on their core standalone app, Synth V Studio Pro 2. 

I'll explain how this all fits into the greater music tech ecosystem below.👇 

🎙️ Dreamtonics: Synth V Pro 2 for musicians

Dreamtonics published the original Synth V software back in 2018. It took them six years and lots of R&D to arrive at version two.

Synth V Pro 2 came out in March 2025, focused on solo voice synthesis. It's a serious musician tool, with a MIDI piano roll and phoneme-level vocal timbre control.

Polyphonic arrangements were *technically* possible in the 2025 version. But stacked, solo vocal stems didn’t deliver the vocal realism of a live choir.

Dreamtonics spent two years researching technical solutions, recording real human choirs (consensually licensed) to train their AI models.

On January 15th, they released three choir voice collections with support for up to 16 vocalists singing in English, Spanish, Japanese, Korean, Mandarin, or Cantonese.

🎹 Better than Suno: Control every note and vocal articulation

Dreamtonics's Synth V Pro 2 outperforms Suno Studio in two major ways; note and timbre control.

Suno does not provide stem-level note manipulation (i.e. autotone). They have a newer audio-to-MIDI feature, but those MIDI notes are divorced from the timbre and lyrics of the original audio file.

Other AI audio-to-midi tool like Hit'n'Mix - RipX or Samplab, or even Celemony Software GmbH's Melodyne Autotune software, let you modify notes in the original audio stem. Suno has not rolled this out yet.

Dreamtonics supports note dictation for custom lyrics AND allows users to edit the pronunciation of every syllable. None of the above audio-to-midi tools support vocal timbre control of this kind.

🗺️ Synth Voices: Mapping the territory

Old school MIDI synth choir patches were limited to vowel tones. Those cheeky "male choir ooh" sounds worked well enough for classic JRPGs and 80s synth ballads, but they're outdated and rarely used anymore.

Modern music software has improved on the timbre of the synth vocals, but are still limited to vowel sounds or random single-word triggers. 

Industry leaders like Spitfire Audio and ARTURIA don't support lyric inputs or phoneme control. They’re ordinary synths.

Choir: Omnia by Native Instruments supports syllable-by-syllable vocal sampling without an AI model, with far less control over notes and pronunciation. 

Choir Omnia costs $400, making it more expensive than Synth V Studio Pro 2 ($99) and a $150 Dreamtonics choir voice collection. 

🥊 TIMEDOMAIN's ACE Studio 2 is the only other AI singing voice DAW that competes with Dreamtonics today. They have a piano roll and AI choir feature.

Controlla and Kits.AI are two simpler, popular AI choir tools for web browser. Controlla is less expensive than Kits and grants users more output minutes per subscription tier.

Music software founder turned fractional PMM. Growth advisor, product manager and copywriter for music tech startups.

As a kid I wanted to be a Fire Truck when I grew up, later on I wanted to become an Inventor.  The idea of using tools and materials in a novel way to solve problems still gets me excited.
By learning to build with code at Epicodus, I have been able to greatly expand my knowledge of Android and Web Development tools.  I've enjoyed engaging in logic-based problem solving, collaboratively exploring new technologies, and developing intuitive UI/UX environments.  
I’m particularly interested in Data Visualization, UI/UX design and implementation, VR, and Android and iOs Development.
When I’m not programming, I enjoy writing and playing music, reading fiction, playing board games, and working on plans for a Transmogrifier to make that Fire Truck dream happen.
