-The pattern for the OSC addresses is as follows: `/chn/1/send/2 <volume>`. This would set the send volume of input `1` to output `2`. The value `<volume>` should be a float, where a value of `0.0` equals -inf dB, `1.0` equals 0 dB and `7.0` equals +18 dB.
+The pattern for the OSC addresses is as follows: `/chn/1/send/2 <volume>`. This would set the send volume of input `1` to output `2`. The value `<volume>` should be a float, where a value of `0.0` equals -inf dB, `1.0` equals 0 dB and `8.0` equals roughly +18 dB.
 
 If you are curious how to calculate this: `dB = 20.0 × log10(float)`
