Sound emulation ПЭВМ "БАЙТ" with КР580ВИ53

[Gelip]

I set 3000KHz in Byte.cfg file to slow down emulation speed.
P.S. Please send me manual how configuration in .cfg file e.g. section mtim : K580wi53 {
What is rate in this setting: clock[0].rate=1/2 Is this is 3500/2=1750KHz ?
At Prusak site read this:

Интересная особенность КР580ВИ53 - при включении питания все три её канала устанавливаются в режим 3 (деление тактовой частоты) с коэффициентом деления 5602. При этом на выходах КР580ВИ53 будет частота 624,7 Гц.

Split rate is 5602 ?
At wikipedia of КР580ВИ53 read this:

Микросхема выпускалась в двух версиях, КР580ВИ53 (i8253) с максимальной рабочей частотой 2 МГц, и КР580ВИ53Д (i8253-5) c максимальной рабочей частотой 2.5 МГц.

At this site http://www.sharpmz.org/mz-700/8253ovview.htm read section Mode 3:

Mode 3 Square Wave Generator

Mode 3 is similar to the mode 2 except that the output will be high for half the period and low for half. If the count is odd, the output will be high for ( n + 1 ) / 2 and low for ( n - 1 ) / 2 counts.

For example, I'll setup counter #0 for a square wave frequency of 10 kHz ( kilo-Hertz ), assuming the input frequency is 1 MHz.

Please refer to the formula described at mode 2.
1 x 106 / 10 x 103 = 100. This is the decimal value to be loaded or the hexadecimal value $0064. The following program example uses the binary load count.

What is rate in this setting: clock[0].rate=1/2 Is this is 3500/2=1750KHz ?

Yes, multiplier 1, divisor 2.

I have used this info. In this document there is a table with divisors, for musical note A (440 Hz) is used 15*256+137=3977. And 3977*440=1749880 Hz, thus the clock frequency of the timer is the half of CPU clock.

OK, clock[0].rate=1/2 is OK but what Lambada in EMU 1.01 is played fast than at oryginal Byte?
Please compare play speed Lambada EMU with Lambada Byte

Trying set main.CPUClock to 3000KHz or 2500KHz but this is detune sound :-(

Is EMU 1.01 have possibility speed down emu speed that F9 speed up?
