YieldStack's answer
AI integrations supporting the platform’s workflows.
we syncopate's answer:
Next.js and React for the site, alphaTab for showing the sheet music and playing it back, MuseScore for the PDFs.
YieldStack's answer
YieldStack combines AI-assisted lender matching with hands-on commercial mortgage brokerage. Borrowers submit once, compare financing options, and work with a team that handles structuring, negotiation, and closing coordination. Borrowers approve lender outreach, with no upfront fees and a broker fee paid only at closing.
we syncopate's answer:
The music is arranged for your instrument, not just copied from another one. Each piece fits its range and key, has a difficulty level, and comes with a piano that plays along. And it’s free.
YieldStack's answer
YieldStack helps borrowers evaluate the whole financing offer: rate, leverage, fees, reserves, prepayment terms, and closing requirements. Its platform organizes the process, while its brokerage team helps borrowers find suitable lenders and move the deal forward. One submission gives borrowers a coordinated financing process without an upfront brokerage fee.
we syncopate's answer:
Tomplay and similar apps charge per piece or per month, and for an instrument like tuba they barely have anything. Here the pieces are free, and you can practise them properly: slow them down, loop the hard bit, play with the piano.

we syncopate's answer:
People who play an instrument that doesn’t get much good sheet music. Right now that’s tuba players, from beginners to advanced amateurs, plus teachers looking for pieces for their students.
YieldStack's answer
Rommin Adl and Daniel Chesney founded YieldStack to simplify commercial real estate financing. The platform brings deal preparation, lender matching, offer comparison, and closing coordination into one workflow, combining AI-assisted analysis with human brokerage expertise.
we syncopate's answer:
I’ve played tuba for about ten years, and finding music for it was always a pain. Most things are written for other instruments, so you end up transposing them yourself, and practising alone without accompaniment gets boring. Most of the great music is public domain anyway, so I started arranging it properly and putting it online for free, with a piano to play along with. Tuba is the start; other instruments come next.
