Leigh Dovetail Jig Instructional Video (Leigh Industries, 1988)

An informational VHS tape showcasing dovetail woodworking tools from Leigh Industries in Vancouver. The tape itself was produced by Force Four Productions in 1988. Very curious about the instruments that play out the intro sequence - there's a very recognizable DX7 EPiano but the rest is unknown to me.
Upscaled to 4K for TH-cam using Lanczos4Resize and deinterlaced with QTGMC, all within StaxRip.
I do not claim to be well versed in the artform of analog media encoding, so I encourage anyone who knows better to give it a try themselves using the RF samples on the archive.org page: archive.org/details/vhs_leigh_dovetail_jig (not yet available)
Rest of description is a direct paste from archive.org page:
This archive includes the FM RF copies of the analogue format (VHS). The media was captured with two modified VTImage capture cards (CXADC) at 40MSPS for the video signal, and 10MSPS for the VHS Hi-Fi audio.
This is the original signal off of the medium before processing past initial signal tracking and pre-amplification - a raw master digital copy or medium transfer.
Capture hardware used: 2x VTImage capture cards (CXADC) sampling at 40MSPS, overclocked via github.com/namazso/cxadc-clockgen-mod
VCR & Tap setup used: Sony SLV-677HF, PB RF pin 2 on CN261 for video FM RF, CN341 pin 3 for VHS Hi-Fi FM RF
TV System & Tape Format: NTSC, VHS SP
