COMPÁS / RHYTHM SECTION FOR THE FM-1

Compás

Que suene
el grupo.

Cumbia, salsa, merengue and bolero. In English or Spanish.

Compás turns the FM-1 into the rhythm section: drums, bass, hand percussion and a 727 full of bongos and congas. You lead from the keys: call the verse, the chorus or the break, and the band comes in on the phrase.

01 / THE BAND

Five pages.
One rhythm section.

The Compás band page
BAND

Call the section.

The center keys cue the song parts. The band waits for the phrase, counts you in on the horn and lands together. ALGORITHM moves the energy: base, lift, break.

The Compás percussion page
PERCUSSION

Conga, maraca, timbal, bell.

Each one comes in and drops out when you call it. Thin the band under a singer, then bring everyone back for the chorus.

The Compás bass page
BASS

A bass that knows the clave.

Ensemble lines for every style, or flip to Acid and let it bite. Tone and Bite are right under your fingers.

The Compás 727 page
727

Fifteen sounds. Hit them.

Bongos, congas, timbales, agogó, cabasa, whistles and the quijada on the pads. Twenty-nine complete rhythms on PRESETS, and a step editor when you want to write your own.

The Compás kumbia page
KUMBIA

Four sounds. Turn them up.

Bombo, güiro, campana and conga with their four factory patterns, from the Hanan Cumbia drum machine. Then push them further than the original goes: drive, decay, pitch and the sample clock itself. Play it alone or layered over the band.

02 / THE MUSIC

From the coast
to the sound system.

29 GROOVE STUDIES

Cumbia, everywhere it went

The Colombian coast, Barranquilla and Soledad. Mexico City sonidera, Monterrey, Puebla and tribal guarachero. Lima, Buenos Aires and Chile. Salsa and son with the clave the right way round, merengue derecho and maco, bolero, tejano and conjunto.

28 WRITTEN SONGS

Play the standards

La Paloma, La Golondrina, Cielito Lindo, La Cucaracha, Siboney, El Manisero and more, arranged from their printed editions, with the melody guide on or off and the key wherever you sing it.

REBAJADA

Slow it down

Take the whole band down to sixty percent, pitch and all, the way Monterrey’s sound systems played their 45s at 33. Then bring it back.

03 / TAKE IT AWAY

For Johnny Canales.

He started his show in Corpus Christi in 1983 and put Tejano, conjunto and regional Mexican bands in front of television audiences across the United States and Mexico. Then he got out of their way: “You got it, take it away!”

Compás opens with him, and he steps back in beside the beat lamps whenever a new song lands. The tribute set runs the band from Tejano cumbia to the standards.

04 / THE CONTROLS

Lead the band.
Not the menus.

Everything you need on a stage is one press or one turn away. The screen shows what is playing, what is coming and how many beats until it lands.
