TR-606 battery size
The at-a-glance entry previously specified four AA batteries. The factory manual specifies four C-size cells (UM-2/R14), providing 6 V, or the original 9 V adaptor specification.

Corrections &
evidence
Our aim is a reference that can be checked. Factory documents, photographs, participant accounts and listening interpretations establish different things. Conflicts and uncertain identifications remain visible.
TR-707 and TR-727 track memory
The earlier text assigned 998 measures to each track. Four tracks share 998 measures in total. Both machine summaries and chapters have been corrected.

TR-909 memory and outputs
The 896-measure capacity applies to each bank, shared across its four tracks. The instrument has ten individual outputs. High Tom is missing from the printed specification list and the later web list, but is visible on the rear panel.

CR-8000 pattern writing
The summary now describes step-by-step writing of two-measure patterns. Its earlier real-time-writing description was incorrect.
TR-707 signal routing
IC40 selects the envelope reference for the converter; IC41 distributes the converted signal to the sample-and-hold lanes. The trigger pulse comes from a separate rear-panel jack driven by the rimshot lane.
INXS: Need You Tonight
The earlier story reversed the journey. Andrew Farriss made the initial demo before his flight to Hong Kong. The revised account also preserves the distinction between the programmed groove and subsequent live playing.
ReBirth and the TR-909
The timeline now identifies ReBirth RB-338 version 2 in 1998, replacing the incorrect 1996 date for its TR-909 implementation.
Dates and recording attributions
Conflicting Roland TR-808 production dates are attributed rather than silently reconciled. The YMO summary identifies the BGM album project. DJ Quik’s CR-8000 identification remains tentative; the Public Enemy summary identifies the demo account. Phil Collins’s CR-78 account distinguishes the preset from added programming.
