In this episode, I head up the A59 to Yorkshire to visit guitarist, guitar‑builder, synth fan, and all‑round studio tinkerer Pete Coates. What starts as a relaxed catch‑up in his workshop turns into a deep dive into his lifelong relationship with music, electronics, DIY gear, and the blend of guitars and synths that shaped both of us. Pete talks about how it all began for him: sneaking his sister’s acoustic guitar, destroying it with an early homemade amplifier, and getting hooked on sound and circuitry. He grew up on Deep Purple, Zeppelin, Sabbath, and The Who, but also fell in love...

Alex from Vulture Culture returns to TDL Synhat to talk Leviasynth, factory patch design, FM architecture, and the strange life cycle of iconic presets. This episode mixes hands‑on sound design stories with broader questions about what makes a synth feel unique — and whether any preset can still define an era. What we cover in the episode Leviasynth first impressions — why it’s more FM‑adjacent than a straight virtual‑analog and where its strengths lie. Factory patch workflow — what it’s like to design presets for unreleased hardware and the surprises that show up...
