v0.6.4 — Hear your tape dumps + a cleaner modal family

JP Patches can now play the FSK tone of your incoming tape dumps through your Mac’s built-in speakers in parallel with the cable — so you actually hear the data come in from your JX-3P (the 1980s cassette-backup sound you grew up with). The send-direction equivalent landed earlier; both directions are wired now.

Also a sweep through every transfer modal to tighten the copy, unify the titles, and surface a long-standing JX-3P gotcha (Memory Protect) before it can quietly eat your transfers.

What’s new

Hear your tape dumps — both directions

• Toggle View → Tape dump sounds on. During Send-to-JX and Record-from-JX, the FSK plays quietly through your Mac speakers in parallel with the cable.
• Per-modal volume slider + mute icon in both flows — adjust on the fly without leaving the modal.
• Off by default. Fully isolated from the actual transfer: a separate audio stream that can’t affect the cable data either way.

Audio Diagnostics (Help → Audio Diagnostics…)

A one-glance check of whether Tape Dump Sounds can find your Mac’s built-in speakers. Green “All systems go!” if the speakers are detected, amber if something’s changed (a recent macOS update may have shifted the speaker label format) with a one-click Report this bug button that opens a pre-filled GitHub Issue containing your device list — paste-and-go for me to ship a fix.

Memory Protect reminder in the Send modal

Both Send-to-JX modals now include a small reminder: “Make sure Memory Protect is off on the JX-3P.” It’s a JX-3P gotcha that silently discards tape-load writes — the transfer looks like it worked from JP’s side but nothing actually saved on the JX. The hint prevents the silent-failure trap.

Cleaner modal family

A pass across both Send-to-JX and Record-from-JX modals to align the visuals, drop dead copy, and improve the order of events:

• New titles: Send sequence to JX-3P / Send C/D banks to JX-3P / Import sequence from JX-3P / Import C/D banks from JX-3P — same shape across all four flows. Dropped the misleading “Step 2 of 2” prefix (which only made sense the first time you calibrated a new audio input).
• New OUTPUT DEVICE block in the Send modal, visually matching the INPUT DEVICE block in Record — so the device routing is surfaced consistently across both directions.
• Cause-effect layout: when the JX starts transmitting (during Record), the JP Patches “receiver” logo + arrow now fade in alongside your JX key diagram — the diagram visually shifts to make room, mirroring the Send modal’s pattern.
• Three-button post-capture warning (Record): when a capture comes in too loud (clipping) or too quiet, you now get a Calibrate button right there — drops you straight into calibration mode so you can lower the gain without canceling and reopening. Use Anyway shifts to red to signal “you probably shouldn’t.”
• Removed time estimates, hint about not switching apps during transfer, and other low-value copy that had accumulated. The timeline communicates duration on its own.
• The “loading: package name” label below the JX-3P logo updates to “✓ complete: package name” when the transfer finishes.
