=== Overview to extensions ===
The second comma in the comma list defines which [[11-limit]] family member we are looking at. Undecimal sensamagic adds [[385/384]], sensawer adds [[441/440]], octarod adds [[100/99]], shrusus adds [[176/175]]. These temperaments use the same generators as sensamagic. Bisector adds [[121/120]] with a half-octave period.
 
Temperaments discussed elsewhere include [[supernatural]] (→ [[Keemic family #Supernatural|Keemic family]]) and [[sensigh]] (→ [[Sengic family #Sensigh|Sengic family]]). The rest are considered below.

Octarod tempers out [[100/99]] and the interval class of [[11/1|11]] is found as a stack of four ~9/7's. The name ''octarod'' was the former name of the sensamagic comma before being reused for this 11-limit extension, and comes from [[octacot]] and [[rodan]]; it should be noted however that rodan does not temper out 100/99 and therefore does not support this temperament.

This is a list showing technical temperament data. For an explanation of what information is shown here, you may look at the technical data guide for regular temperaments.

The sensamagic family of rank-3 temperaments tempers out the sensamagic comma, 245/243.

For a list of rank-2 temperaments, see Sensamagic clan.

Sensamagic

Main article: Sensamagic

Sensamagic is generated by a perfect fifth and a wide supermajor third of ~9/7, two of which make ~5/3. Among the good edo tunings are 87edo and 128edo, as well as the optimal patent val 283edo.

Another notable tuning is given by TE, CTE and POTE, all coinciding at 703.7424 ¢, 440.9020 ¢ with pure octaves since prime 2 is not involved in the comma to begin with, though its difference from CWE is practically unnoticeable.

Overview to extensions

The second comma in the comma list defines which 11-limit family member we are looking at. Undecimal sensamagic adds 385/384, sensawer adds 441/440, octarod adds 100/99, shrusus adds 176/175. These temperaments use the same generators as sensamagic. Bisector adds 121/120 with a half-octave period.

Temperaments discussed elsewhere include supernatural (→ Keemic family) and sensigh (→ Sengic family). The rest are considered below.

Octarod

Octarod tempers out 100/99 and the interval class of 11 is found as a stack of four ~9/7's. The name octarod was the former name of the sensamagic comma before being reused for this 11-limit extension, and comes from octacot and rodan; it should be noted however that rodan does not temper out 100/99 and therefore does not support this temperament.
