DX27/100 Compatibility
DX21/27/100 COMPATIBILITY
The TX81Z uses the same 4-operator, 8-algorithm FM synthesis as the DX21, DX27 and DX100, and voice
data can be transmitted and received between them. However, the TX81Z has a number of features that the
DX21/27/100 does not.
*The Frequency CRS(RATIO) adjustment (p.17) is equivalent to the values programmable in the DX21/
27/100. The FIN(RATIO) adjustment is additional precision available in the TX81Z. Also, the DX21/27/100
operators have no FIX mode.
*The DX21/27/100 operators produce only sinewaves. When a TX81Z voice that uses non-sinewave operators
(p.18) is loaded into a DX21/27/100, it will not sound the same.
*EG RR. The Envelope Generator Release Rate on the DX21/27/100 can be set to 0, whereas the TX81Z
EG-RR minimum setting is 1. When voice data is received from a DX21/27/100, any EG release rates of 0 are
set to 1.
*EG-EG Shift is not a parameter on the DX21/27/100, and will be ignored when you load data from the
TX81Z.
*Parameters which the TX81Z does not have (PEG, chorus) will be set to Off or 0.
*The TX81Z BC Pitch Bias of –50 to +50 (p.22) corresponds to the DX27/100 BC Pitch Bias of 0-99. How-
ever, the curve is different, (Exponential, not linear.)
